Summary: A step-scheme (S-scheme) heterojunction of TiO2/g-C3N4 photocatalysts with enhanced H-2 evolution performance is constructed through a simple chemical vapor deposition process. The microstructure of the samples can be controlled by adjusting the dosage of melamine. The formation of the S-scheme heterojunction in TiO2/g-C3N4 leads to improved photocatalytic performance due to efficient charge separation and high redox ability.

Summary: Controlled oxygen vacancy concentrations can enhance the activity of photocatalytic hydrogen evolution reactions. In this study, Ru/TiO2-x catalysts with varying oxygen vacancy concentrations were synthesized, and the optimal Ru/TiO2-x3 catalyst showed an unprecedentedly high hydrogen evolution rate of 13604μmol·g-1·h-1, which is 45.7 times and 2.2 times higher than that of TiO2-x (298μmol·g-1·h-1) and Ru/TiO2 (6081μmol·g-1·h-1), respectively. Experimental and theoretical results demonstrated that the introduction of oxygen vacancies promotes the hydrogen spillover effect in the metal/support system, and the spillover process can be optimized by modulating the oxygen vacancy concentration. This study proposes a strategy to enhance photocatalytic hydrogen evolution activity by reducing the energy barrier of hydrogen spillover and investigates the effect of oxygen vacancy concentration in the metal/supports system.

Summary: In this study, In2S3 nanosheets, ZnS nanosheets, and ZnIn2S4 nanosheets with sulfur vacancies were synthesized using a facile and rapid microwave-assisted synthesis method. The ZnIn2S4 nanosheets showed a significant energy bandgap value of 2.82 eV and exhibited higher photocatalytic hydrogen production compared to In2S3 nanosheets and ZnS nanosheets under visible-light irradiation. Various factors were evaluated to determine the influence of ZnIn2S4 nanosheets on photocatalytic hydrogen production. The ZnIn2S4 nanosheets also demonstrated the highest photocatalytic hydrogen production from seawater, making it a promising catalyst for visible-light-driven hydrogen production.

Summary: Growing nano-CuO on the surface of CdS nanorods by a simple solution-phase reaction greatly enhances the hydrogen evolution ability of CdS. The loading of CuO nanoparticles does not influence the morphology and crystal structure of CdS, but it can delay electron recombination and improve the hydrogen evolution performance of CdS. The photocatalytic performance of CdS significantly increases after loading with 1 wt% Nano-CuO.

Summary: Compared with crystalline metal sulfides, amorphous metal sulfides can enhance photocatalytic hydrogen-evolution activity by providing more unsaturated S atoms. In this study, amorphous BiSx nanodots were successfully loaded on TiO2 surface as an efficient H-2-evolution cocatalyst, significantly boosting the photocatalytic H-2-production performance. Additionally, the amorphous BiSx nanodots can also serve as a general cocatalyst to promote the H-2-generation activity of other typical photo-catalysts.

Summary: The study introduces an effective electrochemical lithiation method for the synthesis of lithium-intercalated TiO2 nanoparticles, improving their photocatalytic hydrogen production performance. The electrochemical lithiation of TiO2 leads to a partial reduction of Ti ions in the crystal lattices, introducing additional energy states and enhancing the optical properties. As a result, Li-intercalated TiO2 NPs exhibit significantly higher hydrogen generation activity under both UV and visible light exposure compared to commercial TiO2 NPs (P25).

Summary: Nanocomposites of nitrogen-doped TiO2 and reduced graphene oxide were synthesized using a cost-effective microwave-assisted method. The loading of reduced graphene oxide positively affected the photocatalytic activity, especially at lower loading levels. The degradation of organic micropollutants was achieved through a combination of adsorption and photocatalysis, with the specific pollutant type determining the photocatalytic mechanism. Irradiation spectra were found to be more relevant than intensity in the photocatalytic process.

Summary: We prepared Bi4Ti3O12/TiO2 hollow nanocakes via a metal-organic framework (MOF)-derived calcination strategy. The photocatalytic hydrogen generation performance of the nanocakes was enhanced compared to TiO2 hollow nanocakes. The improvement in photocatalytic properties was attributed to the increased specific surface area, as well as the type II heterojunction between Bi4Ti3O12 and TiO2, which enhanced light-harvesting efficiency and suppressed charge carrier recombination.

Summary: Template is commonly used to tune the nanomorphology of photocatalysts, but its influence on precursor polymerization and composition is often overlooked. In this study, a biomass carbon-modified graphitic carbon nitride (CCNx) with a thin-layer morphology was synthesized via one-pot surface-assisted polymerization. The hydrogen bond between melamine and yeast induced strong interfacial confinement, resulting in small-sized CCNx particles. Additionally, the carbon materials derived from yeast significantly improved visible light harvesting, electron delocalization, and charge carrier separation. The optimized CCNx exhibited a much higher photocatalytic hydrogen production rate under visible light irradiation, showing the potential of biomass templates in developing efficient metal-free photocatalysts.
