To　reduce　the　recombination　of　the　photogenerated　charge　carriers　(PCCs),　increase　the　utilization　of　the　PCCs　may　be　an　effective　method.　In　this　work,　the　heterojunction　catalysts　of　MIL-68　derived　In2O3　(IO)　microtube　and　ZnIn2S4　(ZIS)　nanosheets　were　prepared　by　self-template　and　in-situ　growth　strategy.　By　growing　ZnIn2S4　nanosheets　on　the　surface　of　oxygen-deficient　IO　microtube,　these　two　distinct　semiconductors　are　integrated　into　hierarchical　tubular　hybrids　with　heterogeneous　interfacial　contacts.　To　improve　the　utilization　rate　of　PCCs,　the　photocatalytic　CO2　reduction　is　proceeded　on　IO/ZIS　composite　coupling　with　benzyl　alcohol　(PhCH2OH)　oxidation.　With　the　mass　ratio　of　IO　and　ZIS　adjusted,　30%　IO/ZIS　performs　the　best　photocatalytic　activity　of　CO2　reduction,　which　is　64.19　times　higher　than　that　of　pure　ZIS.　The　largely　enhanced　photocatalytic　activity　of　IO/ZIS　is　attributed　to　the　intimate　interfacial　contacts　between　IO　and　ZIS,　which　accelerates　the　separation　and　migration　of　PCCs　via　the　Z-scheme　model.　The　separated　electrons　and　holes　are　respectively　participated　in　the　CO2　reduction　and　the　PhCH2OH　oxidation,　as　the　reduction　and　oxidation　products　are　close　to　1:　1.　This　work　not　only　provides　the　guideline　for　the　design　and　construction　of　complex　semiconductor-based　photocatalysts,　but　an　effective　way　to　increase　the　utilization　of　PCCs.
