Abstract:
Development of efficient and affordable photocatalysts is of great significance for energy
production and environmental sustainability. Transition metal chalcogenides (TMCs) with particle
sizes in the 1–100 nm have been used for various applications such as photocatalysis, photovoltaic,
and energy storage due to their quantum confinement effect, optoelectronic behavior, and their stability.
In particular, TMCs and their heterostructures have great potential as an emerging inexpensive
and sustainable alternative to metal-based catalysts for hydrogen evolution. Herein, the methods
used for the fabrication of TMCs, characterization techniques employed, and the different methods
of solar hydrogen production by using different TMCs as photocatalyst are reviewed. This review
provides a summary of TMC photocatalysts for hydrogen production.
