Photoinduced　charge　separation　and　transfer　have　been　deemed　the　core　factors　affecting　the　efficiency　of　photoelectrocatalysis;　precisely　modulating　the　spatial　migration　of　photo-induced　charge　carriers　to　the　ideal　reaction　sites　is　of　paramount　importance　for　boosting　the　solar　conversion　efficiency　of　photoelectrochemical　(PEC)　cells.　In　this　work,　a　combinatorial　strategy　has　been　developed　to　progressively　construct　highly　efficient　charge　transport　channels　on　the　quintessential　electrochemically　anodized　one-dimensional　semiconductor　framework　(TiO2　nanotube　arrays,　TNTAs)　by　in　situ　annealing-induced　intrinsic　ultrathin　carbon　encapsulation.　Antimony　sulfide　(Sb2S3)　nanocrystals　were　subsequently　attached　to　the　interior　and　exterior　surfaces　of　the　carbon-encapsulated　TNTA　(C-TNTA)　substrate　forming　a　well-defined　ternary　photoanode　(C-Sb2S3-TNTA)　capable　of　triggering　smooth　and　cascade　electron　transfer.　Cooperativity　stemming　from　intrinsic　carbon　encapsulation　on　the　surface　for　fast　electron　transport　in　conjunction　with　Sb2S3　photosensitization　for　substantial　visible　light　harvesting　endows　the　C-Sb2S3-TNTA　heterostructure　with　markedly　enhanced　solar-powered　PEC　water　dissociation　performances,　conspicuously　exceeding　its　single　and　binary　counterparts.　Furthermore,　a　hole　transport　pathway　was　further　constructed　by　site-selective　incorporation　of　an　oxygen　evolving　catalyst　(Co-Pi)　in　the　ternary　system　via　a　photo-assisted　electrodeposition　or　electrodeposition　approach,　which　contributes　to　more　enhanced　separation　efficiency　and　prolonged　lifetime　of　photoinduced　charge　carriers　together　with　improved　photostability.　It　is　expected　that　our　work　would　afford　a　new　frontier　to　intelligently　mediate　the　spatial　directional　flow　of　photogenerated　charge　carriers　and　rationally　construct　efficient　charge　transport　channels　on　the　semiconductor-based　photoelectrodes　for　high-efficiency　solar　energy　harvesting　and　conversion.
