Abstract ：
The development of durable and highly efficient visible-light-driven photocatalysts is essential for the photo- catalytic ozonation process towards degrading organic pollutants. This study presents CN-MA, a novel photo- catalyst synthesized by grafting carbon nitride (CN) with single-atom Mn and 2-hydroxy-4,6-dimethylpyrimidine (HDMP) via one-step thermal polymerization. Experimental characterization and theoretical calculation results reveal that incorporating single-atom Mn and HDMP into CN alters the charge density distribution on the heptazine rings. This modification enhances the absorption of visible light and reduces exciton binding energy, leading to improved separation and migration of photogenerated charge carriers. Moreover, the single-atom Mn provides abundant active sites for O3 adsorption and activation, which increases the utilization of photo- generated electrons to produce highly reactive oxidative species. Consequently, CN-MA exhibits superior photocatalytic ozonation activity, achieving 94% mineralization of phenol within 60 min and maintaining excellent stability over multiple cycles. The research also proposes a plausible reaction mechanism based on free-radical trapping experiments and steady-state concentration experiments using molecular probes. This strategy advances the development of molecular-engineered catalysts co-modified with single metal atoms, thereby enhancing the photocatalytic ozonation process for the degradation of organic pollutants.

Abstract ：
The integration of photoelectrochemical (PEC) technology with persulfate-based advanced oxidation processes has emerged as a promising approach for efficient pollutant removal in environmental remediation. Herein, we developed a novel PEC system combining a Co3O4/BiVO4 (CO/BVO) photoanode with a CoFe2O4/carbon paper (CFO/CP) cathode for activating peroxymonosulfate (PMS) toward bisphenol A (BPA) removal. The enhanced photogenerated charge separation in CO/BVO and the PMS activation by CFO/CP in the PEC system enabled complete BPA degradation within 60 minutes under optimized conditions (1.0 V bias, 1.0 mM PMS). The influence of PMS concentration, applied bias, pH, and coexisting anions on BPA degradation was thoroughly investigated. Radical scavenging experiments combined with electron paramagnetic resonance analysis identified center dot SO4-, center dot OH, and photogenerated holes as dominant reactive species. The system also exhibited good stability over five consecutive cycles, with minimal metal ion leaching. This work demonstrates the potential of an efficient PEC system integrated with sulfate radical-based AOPs, offering an innovative approach for organic pollutant remediation in wastewater treatment.

Abstract ：
Designing porous structures has proven to be an effective strategy for enhancing the photocatalytic NO oxidation activity of carbon nitride (CN). Despite significant advances in the fabrication of porous CN, a cost-effective and high-yield synthesis method for porous CN is still highly desirable. In this study, we presented a facile strategy to synthesize porous carbon nitride by V2O5-assisted thermal oxidation process. Namely, after grinding bulk CN with a small amount of NH4VO3, the mixture was subjected to thermal treatment, resulting in porous carbon nitride with a yield of 50 %. The resulting porous structure, which features an enlarged surface area and enhanced charge separation efficiency, significantly improved the photocatalytic performance for NO removal-approximately four times higher than bulk CN. Additionally, the NO removal mechanism was investigated through in-situ Fourier transform infrared spectroscopy to observe reaction intermediates and electron paramagnetic resonance trapping experiments to identify active species, providing insight into the conversion pathway. The catalytic thermal oxidation etching process effectively tuned the microstructure of g-C3N4, offering a low-cost, easy-to-implement, and time-efficient method for synthesizing porous CN, thereby providing a promising approach for developing advanced photocatalysts.

Abstract ：
Persulfate-based advanced oxidation technology, due to its high efficiency, controllability, and safety, shows great potential for the deep removal of organic pollution, yet its mineralization efficiency is hindered by the lack of synergy between radical and nonradical pathways. Herein, we present defective carbon nitride (DCN) as a highly efficient peroxymonosulfate (PMS) activation catalyst that couples nonradical aggregation with radical mineralization. The tailored electronic structure of the DCN framework enhances visible-light absorption, photogenerated charge separation, and electron transfer ability due to a built-in electric field. DCN effectively interacts with PMS to rapidly accumulate pollutants from the bulk solution onto the catalyst surface via an electron-transfer pathway. Simultaneously, the accumulated pollutants undergo in-situ decomposition by center dot SO4- radicals formed on the catalyst surface under visible light irradiation, achieving a remarkable 98 % mineralization ratio. The mixed-pathway process demonstrates excellent cyclic stability and environmental robustness. This study introduces a novel strategy to enhance the catalytic oxidation performance of metal-free catalysts by controlling persulfate activation pathways for water decontamination.

Abstract ：
A novel pulsed laser-assisted modification was firstly employed to tailor the doping configuration of heteroatoms into graphitic carbon nitride (g-C3N4). Compared with the traditional thermal treatment to form single boron doping configurations (BCN-A), the laser modification could in situ incorporate boron dopants with two distinct configurations (corner (B-(N)3) and bay (H-B-(N)2) motifs) (BCN-L). Experimental characterizations and theory simulations reveal that the cyano group induces defect levels near the valence band (VB) maximum, while its incorporation with the H-B-(N)2 motifs results in the relocation of these defect levels to the vicinity of conduction band (CB) minimum. This modification effectively tunes the band structure of the g-C3N4, enhancing charge separation efficiency and extending the range of light absorption. Moreover, the B-(N)3 motifs at the corners significantly increased surface charge polarization, which boosted the adsorption of oxygen molecules and promoted electron transfer at the catalyst/O2 interface. Density functional theory simulation further revealed that the strong interactions between boron and oxygen atoms could boost oxygen adsorption and promote the formation of intermediate center dot O2- , which represents the initial step in this reaction mechanism. With these beneficial characteristics, the photocatalytic H2O2 production rate of the modified g-C3N4 reached 994.1 mu mol g- 1h- 1, which indicates a significant increase from the 239.6 mu mol - 1h- 1 of the pristine g-C3N4. Furthermore, the optimal BCN-L demonstrated significant photo-corrosion resistance, which maintained high catalytic activity for 10 h of continuous operation without noticeable degradation, achieving a total H2O2 yield of 10.2 mmol g- 1.

Abstract ：
Combining enhanced light absorption capacity with improved directly spatial charge separation efficiency remains a challenging issue for the development of efficient photocatalysts. Herein, we present a strategy for developing anti-Z-scheme poly(thiophene-co-3-ethylthiophene)/K+ implanted polymeric carbon nitride (PB-KCN) heterojunctions, which integrates the two crucial factors of light absorption and directly spatial charge separation. The ratio-optimized 20 PB-KCN exhibits remarkable visible-light-driven hydrogen production activity up to 22.86 mmol/h g−1 (∼61.8 times that of KCN) with a recorded apparent quantum yield of 31.34 % under 550 nm irradiation. Notably, it is confirmed that the efficient photogenerated-carrier separation in PB-KCN heterojunctions is mainly attributed to the firstly proved anti-Z-scheme electron transition with the electrons in the HOMO (highest occupied molecular orbital) of PB directly excited to the LUMO (lowest unoccupied molecular orbital) of KCN, resulting in the spatial separation of photogenerated carriers. The proposed anti-Z-scheme heterojunction solves the problem that traditional heterojunctions cannot achieve synchronous enhancement of light absorption and directly spatial charge separation. © 2024 Elsevier B.V.

Abstract ：
Effective advancements for H2S removal are desperately expected to meet security and ecological necessities as natural guidelines on H2S emissions. Selective catalytic oxidation, as a green technology, has attracted attention owing to its direct conversion of H2S to S without thermodynamic constraints. Herein, we report a carbon-encapsulated WO3 (C@WO3–300) catalyst with nearly 100 % H2S conversion and 99 % S selectivity. Importantly, it likewise accomplishes noteworthy catalytic stability (over 120 h of continuous operation) and water resistance. Excellent durability may be attributed to the ideal porosity of C@WO3, which facilitates the adsorption and activation of H2S and O2. Additionally, the abundant lone pair electrons of carbon support can optimize the chemical environment of WO3-based catalysts and thereby benefit the O2 activation. This study provides a new avenue for the rational design of efficient and durable catalysts for continuous catalytic oxidative desulfurization. © 2024

Abstract ：
A solid-state pulsed laser technique was developed to in situ grow arbitrary immobilized catalysts (Fe3O4, CeO2, WO3 etc.) on the inner surface of quartz tube with robust adhering strength. In a case study, anatase/rutile hetero-phase TiO2 film was deposited to serve as immobilized photocatalysts for the effective removal of antibiotics from aqueous environment. The X-ray absorption spectroscopy, low temperature electron paramagnetic resonance and the density functional theory simulation directly confirm a defect-assisted type-II band alignment was established to facilitate the charge transfer at the hereto-interphase. In addition, the oxygen vacancy enriched anatase phase with greater binding energy towards the dissolved oxygen facilitated the [rad]O2– generation. Meanwhile, the rutile phase enriched with Ti3+ could effectively activate the antibiotics to promote the direct h+ mediated oxidation. Such integration of unique atomic vacancies prevent defects from becoming electron-hole recombination centers and consequently extend the lifetime of the photoexcited charge carrier. The degradation mechanism of oxytetracycline was thoroughly examined by ultra-high resolution electrospray time-of-flight mass spectrometry and Fukui function, while the ecological structure–activity relationships program assessed the toxicity of contaminant to the environment. Milewhile, a continuous water treatment apparatus employing the catalytic tubes as reactors was established and demonstrated a ∼ 95 % OTC degradation under the natural sunlight adopting river water as the background. The experimental studies also claimed that ∼ 90 % of the initial activity could be retained after 100 cycles reuse, which permits their great potential for the applicational scenarios. © 2024

Abstract ：
A solid-state laser scanning treatment(SLST) was adopted to synthesize anatase/rutile TiO_2 heterojunction with effective charge carrier separation and high surface adsorption performances for the photodegradation of sulfamethoxazole(SMX). The 1064 nm pulsed fiber laser could in-situ generate rutile zones on the pristine sheet-like anatase crystal enclosed by(001) facets, which could form the well-defined anatase/rutile interface to promote the formation of dominating active species(h~+ and ·OH) on the anatase zones. X-ray absorption fine structure(XAFS) measurements, low-temperature electron paramagnetic resonance(LT-EPR) as well as the density functional theory(DFT) simulation proved that the oxygen vacancies(V_O) could both introduce defective energy states to promote light absorption and enhance the SMX adsorption on anatase zones. Based on the delicately designed micro-zones, the photodegradation efficiency of the optimized catalyst could reach 99.3%, which demonstrated ～7 times higher performance than t...

Abstract ：
Defect engineering has been widely applied in semiconductors to improve photocatalytic properties by altering the surface structures. This study is about the transformation of inactive WO 3 nanosheets to a highly effective CO 2 - to - CH 4 conversion photocatalyst by introducing surface - ordered defects in abundance. The nonstoichiometric WO 3 - x samples were examined by using aberration - corrected electron microscopy. Results unveil abundant surface - ordered terminations derived from the periodic {013} stacking faults with a defect density of 20.2%. The {002} surface - ordered line defects are the active sites for fixation CO 2 , transforming the inactive WO 3 nanosheets into a highly active catalyst (CH 4 : O 2 = 8.2: 16.7 mu mol h -1 ). We believe that the formation of the W - O - C - W - O species is a critical step in the catalytic pathways. This work provides an atomic - level comprehension of the structural defects of catalysts for activating small molecules.
