The　composite　with　heavily　incorporated　HxWO3　(H0.53WO3/CdS)　was　successfully　synthesized　by　a　facile　method　of　photo-assisted　in　situ　reduction　and　applied　in　photocatalytic　water　splitting　into　H-2.　Its　photocatalytic　activity　is　about　70　times　greater　than　that　of　pure　CdS.　Such　a　heterostructure　shows　wide　spectral　response　in　the　UV-vis-NIR　range,　which　is　attributed　to　the　LSPR　of　H0.53WO3.　In　the　vis-NIR-driven　photocatalytic　water　reduction　process,　a　unique　dual　path　for　generating　H-2　from　water　is　constructed,　which　is　contributed　by　the　synergistic　photocatalysis　effect　between　the　charge-carrier　separation　driven　by　the　Z-scheme　and　hot　electron　injection　induced　by　LSPR　(Localized　Surface　Plasmon　Resonance).
