Summary: In this study, a Z-scheme iron oxyhydroxide/ polymeric carbon nitride (FeOOH/PCN) heterojunction was constructed to overcome the challenges of sluggish water oxidation kinetics and severe charge recombination in solar-driven conversion of carbon dioxide. The FeOOH nanorod provided abundant coordinatively unsaturated sites and oxidative photoinduced holes, enhancing the water decomposition kinetics. PCN acted as a stable agent for CO2 reduction. As a result, FeOOH/PCN achieved efficient CO2 photoreduction with a high selectivity of CH4 (>85%) and an apparent quantum efficiency of 2.4% at 420 nm, surpassing most two-step photosystems to date. This work introduces an innovative strategy for the construction of photocatalytic systems for solar fuel production.

Summary: Graphitic carbon nitride (g-C3N4) is a promising photocatalytic semiconductor, but its photocatalytic activity is limited by electron-hole recombination. In this study, we successfully formed a Z-scheme heterojunction by loading two-dimensional WO3 nanosheets onto the surface of one-dimensional g-C3N4 porous nanotubes. The heterojunction inhibits electron-hole recombination and enhances the photocatalytic activities for hydrogen production and Rhodamine B degradation.

The extraordinary Z-scheme charge transfer manner plays a dominant role in accelerating charge carrier separation and retaining powerful redox ability, while the porous sheet-like nanostructures and oxygen doping positively influence the activity by improving light harvesting, providing plentiful active sites, shortening charge carrier migration distance, and facilitating charge carrier separation.

Summary: Rational design of graphitic carbon nitride (g-C3N4) engineered hematite (Fe2O3)/reduced graphene oxide (rGO) photocatalysts has been successfully employed for visible-light-driven photo-Fenton-like degradation of sulfamethoxazole (SMX). The optimal photocatalyst showed exceptional performance due to the successful integration of g-C3N4/Fe2O3/rGO, enabling efficient separation and migration of photoinduced charge carriers (e/h+). The study also optimized the photochemical decomposition efficiency by analyzing important reaction parameters such as catalyst loading, H2O2 dosage, pH, and temperature, and proposed a possible mechanism for SMX degradation based on the generation of reactive species and degradation intermediates.

Summary: Phosphorus-doped carbon quantum dots (PCDots) were implanted into interlayer carbon nitride nanosheets (PCDots-C3N4) to create a phosphorus-nitrogen (P-N) bridging structure. This new structure enlarged the electronic structure and modulated the plane structure of g-C3N4, while the atomic-level connection by the P-N bridge dramatically extended the delocalization effect and facilitated the intramolecular charge transfer. PCDots-C3N4 exhibited higher efficiency in photodegradation of tetracycline hydrochloride (TC) and bisphenol A (BPA) compared to g-C3N4 and CDots-C3N4, achieving 76% and 100% degradation rate, respectively. This research provides an efficient strategy for rapid electron transfer and offers a new paradigm for wastewater remediation.

Summary: When a membrane is used to treat dye wastewater, the dye molecules accumulate at the membrane surface over time, causing a decrease in membrane flux. Pretreating dye wastewater with layered double hydroxide (LDH) to degrade organic pollutants has been thoroughly investigated in this study. LDH activates peroxymonosulfate (PMS) to produce oxidative free radicals, enhancing the reaction rate. Singlet oxygen (O-1(2)), sulfate radicals (SO4 center dot-), and hydroxyl radicals (center dot OH) were identified as the reactive species. The CoFe-LDH/PMS system showed a high degradation efficiency for Acid Red 27 dye with strong resistance to inorganic ions and pH.

Summary: In this study, it was discovered that the presence of non-active ZnO crystals significantly accelerated the degradation of BPA in the PMS/Co3O4 system, with a 3.7-fold increase in degradation rate. Mechanistic investigation revealed that the ZnO particles generated negative electric microfields around them, which were closely related to the zeta potentials of ZnO and influenced by solution pH. COMSOL simulation showed that the electrostatic repulsion between ZnO and PMS facilitated the migration of HSO5 towards the active Co3O4 surface, leading to an increased concentration of HSO5 around the active Co3O4 particles and improved degradation performance. The particle size of ZnO also had a significant impact on the promoting effect through COMSOL simulation. Therefore, this study provides novel insights into the synergistic effect of electric microfields in enhancing heterogeneous Fenton-like reactions and offers a cost-effective strategy for enhanced persulfate catalysis.

Summary: In this study, the efficiency of carbon quantum dots (CQDs) as photocatalysts is improved by fine-tuning the surface chemistry through selectively substituting surface carbonyl group (C=O) with phenylhydrazine (PH). The modified CQDs-PH show enhanced light absorption and separation of photogenerated electron-hole pairs, leading to boosted generation of reactive oxygen species (ROS) via peroxymonosulfate (PMS) activation. Theoretical calculations demonstrate spatial separation of electrons and holes on CQDs due to the spontaneous surface polarization induced by PH functionalization. This research provides a feasible approach to enhance the photocatalytic activity of CQDs for sustainable water decontamination.

Summary: Photocatalytic hydrogen production is achieved by epitaxial growth of a van der Waals homojunction on an intralayer homojunction of carbon nitride, which enables controlled charge flow. The tandem internal electric field (IEF) in the integrated hybrid, composed of a lateral IEF along the intralayer homojunction and a vertical IEF within the VDW homojunction, facilitates efficient charge separations and mobilities, as well as intensified hydrogen reduction. The hydrogen evolution rate is significantly improved compared to in-planar homojunction and g-C3N4 benchmark, demonstrating the effectiveness of this strategy for robust photocatalysis.

Summary: Designing defects-rich hollow heterostructure bimetal sulfides is an efficient strategy for accelerated monoper-sulfate (MPS) activation. The mono-step sulfidation method was used to develop sulfur vacancy (SV)-rich hollow oxygen-doped Co9S8/Fe7S8 (O-CSFS), which exhibited superior performance due to the highly elec-troactive sites induced by SV and oxygen doping, low charge resistance, and increased conductivity. The ROS-driven pathway and ET-driven pathway were found to be responsible for PCM degradation in the O-CSFS/MPS system, with the ET-driven pathway playing a more significant role.
