- •
We proposed the photocorrosion and recrystallization of CdS on the surface of WS2 nanosheet to resolve the photocorrosion issue.
- •
A highly efficient CdS/WS2 composite photocatalyst with H2 evolution rate increased 56.2 times than pure CdS nanoparticles has been obtained.
- •
CdS/WS2 composite photocatalyst keeps excellent stability in hydrogen generation for more than 200 h without any decrease.
