Controllable　and　precise　design　of　bimetal-　or　multimetal-semiconductor　nanostructures　with　efficient　light　absorption,　charge　separation　and　utilization　is　strongly　desired　for　photoredox　catalysis　applications　in　solar　energy　conversion.　Taking　advantage　of　Au　nanorods,　Pt　nanoparticles,　and　CdS　as　the　plasmonic　metal,　nonplasmonic　co-catalyst　and　semiconductor　respectively,　we　report　a　steerable　approach　to　engineer　the　heterointerface　of　bimetal-semiconductor　hybrids.　We　show　that　the　ingredient　composition　and　spatial　distribution　between　the　bimetal　and　semiconductor　significantly　influence　the　redox　catalytic　activity.　CdS　deposited　anisotropic　Pt-tipped　Au　nanorods,　which　feature　improved　light　absorption,　structure-enhanced　electric　field　distribution　and　spatially　regulated　multichannel　charge　transfer,　show　distinctly　higher　photoactivity　than　blank　CdS　and　other　metal-CdS　hybrids　for　simultaneous　H-2　and　value-added　aldehyde　production　from　one　redox　cycle.
