Energy crisis around the world pushes people to take advantage of renewable energy. As one kind of photosynthesis, H2 evolution from water splitting through solar light attracts a lot of interest. Herein, this article will introduce recently published CdS-based semiconductors for photocatalytic hydrogen evolution from water splitting under solar light. The activity and stability of different CdS-based photocatalysts including CdS with different nanostructures, CdS composites with other semiconductor, polymer or high surface area materials will ...
