Biomimetic nitrogen-rich photocatalyst based on cadmium sulfide for photocatalytic hydrogen evolution.

A novel N-rich sugarcane-like photocatalyst CdS/CN (CCN) was prepared by a thermal polymerization method and tested for generating H and realizing antiphotocorrosive performance. The best photocatalytic H evolution is obtained for a CdS to CN mass ratio of 1:1 (CCN3), which is nearly 33 and 3 times higher than that of pure CN and CdS, respectively. CCN3 can be used to effectively reduce CdS photocorrosion and increase stability because of its N-rich performance and sugarcane-like structure, which can affect electron transport and enhance the internal binding force, respectively.
