Microwave Assisted Ion Exchange Synthesis and Enhanced Visible Light Photoactivity of Graphene CdS/CuS Nanoplates.
A novel reduced graphene oxide graphene CdS/CuS nanoplate (G CdS/CuS NP) was fabricated using a microwave method of loading CdS nanoplates onto graphene sheets (G CdS NP) and subsequent cation exchange between G CdS NP and Cu(NO3)2. The prepared G CdS/CuS NP exhibited excellent photocatalytic activity which was attributed to the synergy between graphene and CdS/CuS NP. The heterostructure in the CdS/CuS NP lead to an efficient charge transport across the interface. Graphene facilitated the transformation of electrons and reduced the recombination of electron hole pairs. These results provide a fabrication method for highly active photocatalysts and will lead to future rational design of photocatalytic materials.
