摘      要：A novel cocatalyst,*** nickel nanoparticles encapsulated in few-layer graphene(Ni@C),is obtained by carbonization of metal–organic frameworks(MOF)and leaching treatment of hydrochloric *** is selected as the cocatalyst for CdS nanosheets,forming CdS-Ni@C *** remarkably improves the photocatalytic activities of CdS nanosheets due to the synergistic effect of Ni nanoparticles and graphene *** addition,the Ni nanoparticles encapsulated by graphene layers effectively isolate Ni from the ambient,which avoids contamination and curbs *** larger work function of Ni@C and outstanding conductivity of graphene promote the electron transfer from CdS to Ni@C,suppressing the recombination of photogenerated carriers and facilitating the separation of photogenerated electronhole *** strategy by adopting this novel cocatalyst provides a new solution to the improvement of the photocatalytic hydrogen production.
