Summary: A novel 3D hierarchical CdS/NiAl-LDH photocatalyst consisting of 1D CdS nanorods and 3D flower-like NiAl-LDH microspheres was successfully fabricated by an electrostatic assembly strategy. The CNA-20 hierarchical photocatalyst exhibited the optimum hydrogen evolution rate of 3.24 mmol g-1 h-1 under visible irradiation, which was 6.23 times higher than that of pure CdS. A type-II charge transfer mechanism was proposed based on energy band structures and first-principles calculation. The designed synergistic 1D/3D interface interaction effectively promoted the rapid separation and migration of photogenerated charges, thus facilitating H2 evolution.

Summary: This paper investigates the preparation of Ca-doped BFO nanoparticles and BCFO-CdS nanocomposites. The study reveals that Ca doping narrows the band gap of BFO, leading to better absorption of visible light. Among all the samples, the BCFO-CdS nanocomposites with a reaction time of 10 minutes exhibit the best photocatalytic performance. The degradation rate can be further enhanced after electric polarization. These findings provide valuable insights for designing highly efficient photocatalysts.

Summary: This study constructed a series of pyrene-alt-dibenzothiophene-S,S-dioxide (P16PySO)/tungsten trioxide (WO3) composites to investigate the mechanism of photocatalytic styrene oxidation under anaerobic and aerobic conditions. The S-scheme charge transfer pathway within P16PySO/WO3 was systematically analyzed. The results revealed that triplet oxygen (O-3(2)) could efficiently trap the energy of triplet excited P16PySO through an energy transfer process and convert to singlet oxygen (O-1(2)), which played an important role in styrene oxidation.

Summary: The slow oxygen evolution reaction (OER) was replaced by selective benzyl alcohol (BA) oxidation to benzaldehyde (BD) to promote H2 production. The CdS quantum dots, modified with Co2+ hole cocatalysts, were used as photocatalysts to accelerate the rate-limiting BA oxidation. The photocatalytic system exhibited a high H2-production rate and a remarkable apparent quantum yield under 365-nm light irradiation. This work exemplifies a bifunctional photocatalytic system for simultaneous production of self-separated hydrogen and benzaldehyde, both of which are important industrial products.

Summary: Defect engineering modified graphite carbon nitride (g-C3N4) with dual defect sites, -C N groups and N vacancies, has been found to significantly enhance the photocatalytic production of H2O2. The dual defect sites form an electron-rich structure and lead to a more localized charge density distribution, which improves light absorption, carrier separation, selectivity, and activity of H2O2 generation. The N vacancies effectively adsorb and activate O-2, while the -C N groups facilitate the adsorption of H+, synergistically promoting H2O2 generation. The modified g-C3N4 achieved a high H2O2 generation rate and apparent quantum efficiency, surpassing previously reported g-C3N4-based photocatalysts.

The NCs exhibited enhanced charge separation and visible light harvesting due to the presence of defect sites in ZnS. Characterization techniques including XRD, TEM, SEM, XPS, EDAX, and FTIR confirmed the composition, structure, and purity of the synthesized NCs. The photodegradation of RhB by ZnS/CdS NCs reached a maximum of 99.18% in 120 min, showing significantly higher efficiency compared to pure ZnS and CdS. The defect engineering played a vital role in enhancing the photocatalytic activity of the NCs, which was further supported by PL spectra and EIS analysis.

Summary: Metal chalcogenides (MSx) as H-2-evolution cocatalysts often have poor H desorption properties due to strong interfacial interactions with electronegative S sites, hindering the release of free H-2. A universal strategy involving electron-enriched regulation of sulfur-active sites by introducing W heteroatoms into MoS2+x has been developed to weaken S-Hads bonds and enhance hydrogen-evolution activity. This study demonstrates the importance of optimizing electron densities at active sites for the development of efficient catalytic materials.
