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.
