In　order　to　obtain　the　high　H-2　evolution　activity,　an　inexpensive　and　efficient　photocatalyst　CdS　nanorods　decorated　with　NiCd　bimetallic　nanoparticles　has　been　designed　and　successfully　prepared　via　an　ingenious　in　situ　deposition　method.　The　experiment　results　indicate　that　NiCd　bimetallic　cocatalysts　can　efficiently　inhibit　the　recombination　of　the　photoinduced　electron-hole　pairs　and　promote　the　interfacial　charge　transfer,　resulting　in　a　significant　improvement　in　photocatalytic　H-2　production　performance.　The　NiCd/CdS　NRs　sample　exhibits　an　excellent　photocatalytic　H-2　evolution　activity　under　visible　light　irradiation　(lambda　＞　410　nm),　and　the　corresponding　H-2　evolution　rate　is　11.57　mmol.h(-1).g(-1)　,　which　is　about　64.8,　17.2　and　2.3　times　as　that　of　pristine　CdS　NRs,　Cd/CdS　and　Ni/CdS,　respectively.　This　work　is　expected　to　provide　a　new　inspiration　for　rationally　designing　highly　efficient　and　practical　hybrid　photocatalyst　systems.
