Abstract：

The　n-type　CuInS2　nanoparticles　were　deposited　successfully　on　n-type　TiO2　nanotube　surface　via　the　successive　ion　layer　absorption　and　reaction　(SILAR)　technique.　Compared　with　the　pure　TiO2,　the　photoresponse　of　CuInS2/TiO2　films　is　expanded　to　the　visible　region,　indicating　an　excellent　visible　light　utilization　rate　and　improved　photoelectric　conversion　efficiency.　Benefiting　from　the　favorable　n-n　heterojunction　structure,　the　photocurrent　density　of　CuInS2/TiO2　photoanode　under　visible　light　irradiation　exceeded　40　μA/cm2,　which　was　8　times　that　of　the　TiO2.　The　potential　of　the　coupled　316L　stainless　steel　in　3.5　wt%　NaCl　aqueous　solution　was　droped　by　−　850　mV　in　the　presence　of　CuInS2/TiO2　films,　which　showed　a　remarkable　photocathode　protection　performance　of　n-n　type　CuInS2/TiO2　heterojunction　materials.　©　2021　Elsevier　B.V.
