Ultrafast charge separation in a WC@C/CdS heterojunction enables efficient visible-light-driven hydrogen generation† Lu Chen, *a Feng Chen,a Shaoming Ying, a Ruowen Liang,a Guiyang Yan, a Xuxu Wang *b and Yuzhou Xia*a Abstract The rapid recombination of photogenerated carriers and strong photocorrosion have considerably limited the practical application of CdS in the field of photocatalysis. Loading a cocatalyst has been widely utilized to largely enhance photocatalytic activity.
