Recent research progress of bimetallic phosphides-based nanomaterials as cocatalyst for photocatalytic hydrogen evolution

Chunmei Li et al.

Summary: Hydrogen energy is considered a potential candidate for replacing traditional fossil fuels due to its high combustion heat value and low environmental pollution. Photocatalytic hydrogen evolution from water splitting is a promising technology to convert solar energy into sustainable H-2 fuel. Developing high-activity semiconductor materials is crucial for efficient hydrogen evolution in photocatalysis. Transition metal phosphides have shown advantages as co-catalysts, and bimetallic phosphides have attracted attention due to their lower overpotential, superior conductivity, and better charge carriers transfer impedance. This minireview summarizes the latest developments of bimetallic phosphides in photocatalytic reactions, including loading methods, efficiency in H-2 evolution, and application under dye sensitization effect.

Unraveling fundamental active units in carbon nitride for photocatalytic oxidation reactions

Chaofeng Huang et al.

Summary: By synthesizing CN with more detailed molecular structures, we clarified the fundamental active units in photocatalysis, with M1 responsible for light absorption and M2 for charge separation. Additionally, oxygen molecules were found to participate in the photoexcited processes. As a result, this CN showed higher activity, up to 8 times that of traditional bulk CN for photocatalytic oxidation.
