Abstract ：
Tetracycline (TC) antibiotics, extensively utilized in livestock farming and aquaculture, pose significant environmental challenges. Photocatalysis, leveraging renewable sunlight and reusable photocatalysts, offers a promising avenue for mitigating TC pollution. However, identifying robust photocatalysts remains a formidable challenge. This study introduces a novel hollow -flower -ball -like nanoheterojunction composed of a nitrogen -rich covalent organic framework (N-COF) coupled with BiOBr (BOB), a semiconductor with a higher Fermi level. The synthesized N-COF/BOB S -scheme nanoheterojunction features an expanded contact interface, strengthened chemical bonding, and unique band topologies. The N-COF/BOB composites showcased exceptional TC degradation performance, achieving an 81.2% removal of 60 mg/L TC within 2 h, markedly surpassing the individual efficiencies of N-COF and BOB by factors of 3.80 and 5.96, respectively. Furthermore, the total organic carbon (TOC) removal efficiency highlights a superior mineralization capacity in the N-COF/BOB composite compared to the individual components, N-COF and BOB. The toxicity assessment revealed that the degradation intermediates possess diminished environmental toxicity. This enhanced performance is ascribed to the robust Sscheme nanoheterojunction structure, which promotes efficient photoinduced electron transfer from BOB to NCOF. This process also augments the separation of photogenerated charge carriers, resulting in an increased yield of superoxide radicals (center dot O2 ) and hydroxyl radicals (center dot OH). These reactive species significantly contribute to the degradation and mineralization of TC. Consequently, this study introduces a sustainable approach for addressing emerging antibiotic contaminants, employing COF-based photocatalysts.

Abstract ：
The treatment of emerging contaminants is essential but challenging. Herein, a novel MOF/PAN fibrous composite (TCPP@UiO-66/PAN) was synthesized and used as a self-cleaning membrane for the efficient removal of a typical emerging contaminant, diclofenac sodium (DF). The introduction of the secondary linker tetra(4carboxyphenyl)porphyrin (TCPP) served to expand the pores and enhance its photocatalytic activity. TCPP@UiO-66/PAN shows higher adsorption capacity and initial adsorption rate than UiO-66/PAN. The maximum adsorption capacity of DF on TCPP@UiO-66/PAN reached 202 mg/g by Langmuir model. The DF adsorption mechanism involves the pi-pi/anion-pi interaction, Lewis acid-base interaction, and hydrogen bonding. Based on the dynamic filtration experiment, TCPP@UiO-66/PAN exhibited a remarkable treatment capacity for DF-contaminated water, measuring 3.75 x 104 kg/kg. Given its fibrous membrane structure, TCPP@UiO-66/ PAN could be easily separated from water and reused. In-situ photo-regeneration emerged as a highly effective method for regenerating TCPP@UiO-66/PAN after reaching adsorption saturation, with over 95 % DF degradation achieved under sunlight irradiation. The decomposition of DF primarily resulted from the generation of h+ and 1O2. Additionally, TCPP@UiO-66/PAN exhibited notable antibacterial properties when exposed to visible light. In vitro cytotoxicity assessments further confirmed the safety of these MOF/PAN composites. Combining the advantages of hybrid-linker strategy and fibrous composite, this work provided new insight into constructing MOF-based functional material for wastewater purification.

Abstract ：
Designing photocatalysts with well-defined structure-function relationships is imperative for propelling the progression of desired photocatalytic oxidation. Herein, the efficient conversion of solar energy to H2O2 and subsequently to hydroxyl radicals (•OH) is achieved through a synergistic interplay between olefin linkage (-C[dbnd]C-) and spatially separated benzene-triazine dual reaction sites within covalent organic frameworks (COFs). The upgraded -C[dbnd]C- can increase the conjugation degree of COFs, which establishes an expanded superstructure for boosting charge separation/transfer and stability. This precise modulation renders more opportunities for the hot electrons to migrate to the benzene site for solar-to-H2O2 generation, and to the triazine site for H2O2-to-•OH, separately. The optimized •OH generation pathway enables remarkable oxidation performances against recalcitrant organic pollutants, and pathogenic microorganisms under visible light irradiation. This work provides new insights for tuning the synergistic interactions of various building blocks within the COFs for the selective generation of highly reactive •OH for environmental remediation. © 2024 Elsevier B.V.

Abstract ：
Semiconductor-based solar-driven CO2 to fuels has been widely reckoned as an ingenious approach to tackle energy crisis and climate change simultaneously. However, the high carrier recombination rate of the photocatalyst severely dampens their photocatalytic uses. Herein, an inorganic-organic heterojunction was constructed by in-situ growing a dioxin-linked covalent organic framework (COF) on the surface of rod-shaped beta-Ga2O3 for solar-driven CO2 to fuel. This novel heterojunction is featured with an ultra-narrow bandgap COF-318 (absorption edge = 760 nm), which is beneficial for fully utilizing the visible light spectrum, and a wide bandgap beta-Ga2O3 (absorption edge = 280 nm) to directional conduct electrons from COF to reduce CO2 without electron-hole recombination occurred. Results showed that the solar to fuels performance over beta-Ga2O3/COF was much superb than that of COF. The optimized Ga2O3/COF achieved an outstanding CO evolution rate of 85.8 mu mol h(-1).g(-1) without the need of any sacrificial agent or cocatalyst, which was 15.6 times more efficient than COF. Moreover, the analyses of photoluminescence electrochemical characterizations and density functional theory (DFT) calculations revealed that the fascinate construction of beta-Ga2O3/COF heterojunction significantly favored charge separation and the directional transfer of photogenerated electrons from COF to beta-Ga2O3 followed by CO2. This study paves the way for developing effective COF-based semiconductor photocatalysts for solar-to-fuel conversion.

Abstract ：
Covalent organic frameworks (COFs) are crystalline porous materials with enormous potential for realiz-ing solar-driven CO2-to-fuel conversion, yet the sluggish transfer/separation of photoinduced electrons and holes remains a compelling challenge. Herein, a step (S)-scheme heterojunction photocatalyst (CuWO4-COF) was rationally fabricated by a thermal annealing method for boosting CO2 conversion to CO. The optimal CuWO4/COF composite sample, integrating 10 wt% CuWO4 with an olefin (CC) linked COF (TTCOF), achieved a remarkable gas-solid phase CO yield as high as 7.17 +/- 0.35 lmol g-1h-1 under visible light irradiation, which was significantly higher than the pure COF (1.6 +/- 0.29 lmol g-1h-1). The enhanced CO2 conversion rate could be attributable to the interface engineering effect and the formation of internal electric field (IEF) directing from TTCOF to CuWO4 according to the theoretical calculation and experimental results, which also proves the electrons transfer from TTCOF to CuWO4 upon hybridization. In addition, driven by the IEF, the photoinduced electrons can be steered from CuWO4 to TTCOF under visible light irradiation as well-elucidated by in-situ irradiated X-ray photoelectron spectroscopy, verify-ing the S-scheme charge transfer pathway over CuWO4/COF composite heterojunctions, which greatly foster the photoreduction activity of CO2. The preparation technique of the S-scheme heterojunction pho-tocatalyst in this study provides a paradigmatic protocol for photocatalytic solar fuel generation. (c) 2023 Elsevier Inc.

Abstract ：
Tetracycline (TC), a widely employed broad-spectrum antibiotic with global prevalence, possesses the ability to infiltrate soil matrices and potentially reach groundwater systems, thereby posing a consequential human health risk. To address this concern, a novel NiFe-mixed metal oxides (MMO) composite was synthesized and employed within quartz sand as a strategic measure to regulate the downward migration of TC. In-depth investigations of TC transport behavior in quartz sand, complemented by NiFe-MMO, were conducted via a series of rigorous batch and saturation-filled column experiments. The impacts of NiFe-MMO dosage, ionic strength, cationic types, solution pH, and flow rates on TC transport were systematically and comprehensively scrutinized. Our findings reveal that even minute quantities of NiFe-MMO prompt substantial TC adsorption, facilitated by electrostatic interactions and surface complexation, notably in low-concentration background solutions. Additionally, the presence of Ca2+ engenders a bridging effect, further enhancing TC adsorption onto the sand. These significant observations bear far-reaching implications in elucidating the fate of antibiotics within the intricate interplay of soil and groundwater domains. The strategic amalgamation of NiFe-MMO and quartz sand offers innovative prospects for managing TC dissemination, thereby augmenting endeavors toward sustainable environmental protection.

Abstract ：
Photocatalytic conversion of CO2 into value-added products is considered a sustainable strategy to mitigate CO2 over-emission. However, achieving favorable performance generally relies on valuable additives such as sacrificial organic electron donors, which, in turn, limit its applicability. In this study, we tested dissolved effluent organic matter (dE(f)OM) derived from domestic wastewater as an alternative hole scavenger during CO2 photoreduction over a ternary photocatalyst (CTF-1-Bi-BiOBr) composed of CTF-1, Bi, and BiOBr. Impressively, the optimal CTF-1-Bi-BiOBr catalyst demonstrated remarkable dE(f)OM degradation and CO production (2.933 mu mol g(-1) h(-1)) in a cascading oxic-anoxic photocatalytic process. This enhanced activity was attributed to the establishment of an S-scheme structure between CTF-1 and BiOBr, with Bi-metal serving as the carrier recombination centre, allowing holes and electrons with greater redox capacity to be retained. Importantly, we discovered that smaller intermediates formed during the oxic stage can serve as extraordinary electron donors in the succeeding anoxic stage. Spectroscopic and electrochemical characterization techniques revealed that pre-oxidized dE(f)OM was more effective in preventing the recombination of photoinduced carriers compared to untreated dE(f)OM, highlighting its improved electron donating propensity. This study provides innovative insights for simultaneously achieving wastewater purification and carbon emission reduction through a more economical pathway.

Abstract ：
Solar-driven photocatalytic hydrogen peroxide (H2O2) production presents a promising avenue for achieving sustainable water disinfection. However, the development of a robust and durable system for practical applications remains a notable and unresolved challenge. Herein, a star photocatalyst, the covalent organic frameworks (COFs), was modified with CdS for boosting environmentally benign H2O2 synthesis. Under simulated sunlight and without sacrificial reagents, the composite material exhibited a boosting capacity for H2O2 production, which was attributable to the establishment of a "step" (S)-scheme transfer pathway and facilitation of adequate oxygen diffusion. Nevertheless, it was found that photocatalytically derived H2O2 alone exhibited inefficient disinfection performance, whereas the addition of Fe-(II) allowed rapid inactivation of Escherichia coli, emphasizing the pivotal importance of integrating photocatalysis and Fenton reactions within the photocatalytic H2O2 production system. Furthermore, a dual-compartment reactor, employing a semipermeable membrane, was devised to spatially segregate photocatalysts from microorganisms. Such an operation mode enabled H2O2 diffusion from the photocatalytic compartment to the microbial compartment, thereby achieving a "long-distance" sterilization manner and simultaneous consummating recovery strategy of the photocatalysts. This study not only provides a paradigmatic approach for boosting the production of H2O2 from a COF-based material but also illuminates an innovative technological option for sustainable photocatalytic-based water disinfection.
