Abstract ：
Polymeric carbon nitride (PCN) photocatalysts have the potential to remove NO from ambient air. However, the catalytic performance of PCN is limited by the lack of sufficient active sites to effectively activate molecular oxygen. Herein, we report the construction of photocatalysts consisting of defective-activated-carbon and PCN via amide bond formation. This photocatalyst not only significantly enhances the chemisorption of O2, but also accelerates the activation of molecular oxygen and oxidation of NO by creating a new electron transport pathway. This work provides a new strategy for polymer photocatalysts to promote molecular oxygen activation by constructing close-contact interfaces through amide bonding. © 2024 Elsevier B.V.

Abstract ：
Photocatalytic ozonation emerges as an appealing approach for wastewater purification. However, the kinetic constraints associated with the charge separation and the ozone activation hinder the advancement of photocatalytic ozonation systems. Herein, we prepared CeO2 photocatalysts with predominantly exposed {1 1 0}, {1 0 0}, or {1 1 1} facets, highlighting the synergy role of crystal facet and oxygen vacancies in manipulating electron transfer and ozone activation. The CeO2-{1 1 0} catalyst exhibits the best efficiency for phenol mineralization (69%) in photocatalytic ozonation. Ex-situ, Quasi-situ, and In-situ characterization of the CeO2 catalysts reveal that facet engineering in the CeO2 catalysts optimizes the electronic properties of the catalysts, thereby enhancing the separation of photogenerated charge carriers and transfer of electrons and holes, which provides more electrons for O3 activation and promotes the formation of reactive oxygen species (ROS). Moreover, facet modulating leads to a change in the density of surface oxygen vacancies. The increased oxygen vacancy density on the CeO2-{1 1 0} surface accelerates the activation of O3 and the formation of adsorbed oxygen (*O), synergistically boosting the production rate of ROS. The present study offers valuable insights into the design of efficient photocatalysts for wastewater purification. © 2024 Elsevier Inc.

Abstract ：
Halide perovskites and derivatives have been used as emerging photocatalysts due to their unique optoelectronic and structural diversity. However, compared with the well-explored photophysical processes for light-driven more energetic carriers to trigger redox reactions, catalytic effects on the surface of halide perovskite or their derivatives for chemical transformations between reactive species are seldom addressed, which is equally important for improving the efficiency for halide perovskite-based photocatalysts. Here, we demonstrate that Cs3Bi2Br9 sites in the Cs3Bi2Br9/CdS heterojunction, not only participate in light-driven processes, but also play a vital role for the activation and conversion of key intermediates during C(sp3)-H bond transformation, via a more thermodynamically and kinetically favorable surface reaction pathway. Besides, various aromatic hydrocarbons can be effectively photocatalytic converted to corresponding aldehydes/ketones as major products. This work highlights the importance of surface catalysis mechanism in photocatalysis not only for halide perovskites but also for other semiconductors.

Abstract ：
The photoresponse and photocatalytic efficiency of bismuth oxychloride (BiOCl) are greatly limited by rapid recombination of photogenerated carriers. The construction of porous single-crystal BiOCl photocatalyst can effectively alleviate this issue and provide accessible active sites. Herein, a facile chelated ion-exchange strategy is developed to synthesize BiOCl mesoporous single-crystalline nanosheets (BiOCl MSCN) using acetic acid and ammonia solution respectively as chelating agent and ionization promoter. The strong chelation between acetate ions and Bi3+ ions introduces acetate ions into the precipitated product to exchange with Cl- ions, resulting in large lattice mismatch, strain release, and formation of void-like mesopores. The prepared BiOCl MSCN photocatalyst exhibits excellent catalytic performance with 99% conversion and 98% selectivity for oxidation of benzyl alcohol to benzaldehyde and superior general adaptability for various aromatic alcohols. The theoretical calculations and characterizations confirm that the superior performance is mainly attributed to the abundant oxygen vacancies, plenty of accessible adsorption/active sites and fast charge transport path without grain boundaries.

Abstract ：
Constructing low-dimensional heterojunctions via hybridizing 0D, 1D, and 2D building blocks is an effective means to devise higher-order architectures with excellent photocatalytic reaction activities. Developing a versatile topology optimization strategy paves the way for guiding the rational structural design of a wide range of heterostructures. Herein, taking the ZnO-CdS hybrids with mixed topology structures (including 0D-1D, 0D-0D, and 1D-1D composites) as a model system, the work unveils a ubiquitous, yet unrecognized, topology dependence of photocatalytic performances and the 0D-1D topology combination coupled with an annealing treatment gives rise to an optimal photocatalytic redox activity, far exceeding those of 0D-0D and 1D-1D counterparts. The 0D-1D topology integrates the structural merits of both constituent units, where the 1D unit acts as a rigid matrix to allow the uniform dispersity of 0D units for exposing abundant active sites, and a mobile 0D unit contributes to the interfacial reconstruction for forming charge-migration-expediated heterointerfaces via thermal-induced grain rotations. Such thermal-annealing-coupled topology optimization methodology shows applicability for a large spectrum of low-dimensional heterojunctions, offering a prototype for the precise structural design of low-dimensional heterojunctions with enhanced catalytic performance.

Abstract ：
Supported metal nanocatalysts are promising candidates for heterogenous photocatalysis because the metal nanoparticles (e.g., Au, Pt, or Pd) loaded on the semiconductor surface not only act as a reductive cocatalyst, which accelerates the kinetics of reactions such as H+ reduction, but also trap the photoelectrons, which allows charge separation. Owing to these unique benefits, supported metal photocatalysts have been extensively studied for green H2 production at the reductive side integrated with organic selective oxidation at the oxidative side in a closed photocatalytic redox cycle. Imines and their derivatives are important chemicals in the industrial production of functional polymers, agrochemicals, and pharmaceuticals. Recently, imines have been successfully produced via the photocatalytic dehydrogenative coupling of amines over supported metal nanocatalysts. However, owing to the strong adsorption of H atoms and imines on the metal surface, the produced imines are converted to secondary amines via a self-hydrogenation process, thus greatly decreasing the selectivity toward the desired imines. Herein, we demonstrate that the construction of an ultrathin carbon layer on a Pd/TiO2 photocatalyst (Pd/TiO2@C) via the thermal annealing of self-assembled polydopamine layers is a simple yet effective strategy to address this issue. Temperature-programmed reduction of hydro -oxygen titration and cyclic voltammetry curves for Pd/TiO2 vs. Pd/TiO2@C indicate that the conformable coating of the carbon layer on the catalyst surface facilitates kinetic control of H atom adsorption on the supported Pd nanoparticles. Furthermore, in situ Fourier-transform infrared spectroscopy demonstrates that the conformably coated ultrathin carbon layer also decreases the adsorption of substrate molecules such as N-benzylidenebenzylamine on the catalyst surface, which weakens their interaction with the supported Pd nanoparticles. Thus, the construction of an ultrathin conformable carbon coating on Pd/TiO2 is a facile strategy to kinetically control the adsorption behavior of H atoms and imines on the Pd surface during photocatalytic redox reactions, which can suppress the excessive hydrogenation of imines toward selectivity improvement. In addition, owing to the strong electronic interaction between the Pd nanoparticles and the carbon layer, the encapsulated Pd nanoparticles retain their unique catalytic properties toward the H2 evolution reaction. As a result, Pd/TiO2@C with an optimized carbon layer thickness facilitates improved photocatalytic synthesis of imines, with conversion and selectivity as high as 95% and 99%, respectively. This study provides an effective strategy to develop high-performance supported metal nanocatalysts for integrated photocatalytic systems to produce H2 and valuable organic chemicals.

Abstract ：
The activation of peroxymonosulfate (PMS) over carbon nitride-based photocatalysts towards refractory organic removal has received growing attention in wastewater treatment. In this study, we successfully synthesized copper single atoms incorporated into crystalline carbon nitride (Cu-CCN) and applied it to activate PMS towards bisphenol A (BPA) removal. The characterization and theoretical calculation results indicated that Cu-CCN had good crystallinity, outstanding charge separation and transfer ability, and numerous PMS adsorption and activation sites provided by Cu single atoms. Consequently, Cu-CCN demonstrated an enhanced ability to activate PMS for BPA degradation. The activity performance of Cu-CCN was affected by the experimental conditions at different levels, and the catalyst had good stability in structure and activity during cyclic runs. A plausible reaction mechanism was also proposed according to free radical trapping and quenching experiments. This oxidation process can efficiently degrade organic pollutants as well as reduce the toxicity. The findings of this work elucidated an efficient photocatalyst for activating PMS towards organic removal and might guide the design of other metal single-atom modified photocatalysts.

Abstract ：
The persulfate-based nonradical reaction process has gained increasing attention in removing organic contaminants, and the process dramatically needs affordable, robust, high-performance heterogeneous catalysts. Herein, dimethyl formamide (DMF) incorporated graphitic carbon nitride (DCN) was synthesized. The molecular engineering of the heptazine unit in DCN improves the electron mobility, strengthens the built-in electric field, and provides abundant active sites, thus enabling DCN to efficiently activate PMS for organic degradation, with 100 % removal of BPA within 12 min. The investigation of the reactive species and electrochemical properties confirmed the direct electron transfer in the PMS activation for organic degradation over DCN. More importantly, DCN can be used as a membrane catalyst in a flowing catalytic unit, enabling continuous water purification and catalyst regeneration. This work provides novel guidance for metal-free catalyst design and profound insights into the persulfate-based heterogeneous catalytic oxidation process for water decontamination technology.
