The　conversion　of　solar　energy　in　a　wide　spectrum　region　to　clean　fuel,　H2,　remains　a　challenge　in　the　field　of　photocatalysis.　Herein,　plasmonic　TiN　nanobelts,　as　a　novel　cocatalyst,　were　coupled　with　CdS　nanoparticles　to　construct　a　0D/1D　CdS/TiN　heterojunction.　Utilization　of　the　localized　surface　plasmon　resonance　(LSPR)　effect　generated　from　TiN　nanobelts　was　effective　in　promoting　light　absorption　in　the　near-infrared　region,　accelerating　charge　separation,　and　generating　hot　electrons,　which　can　effectively　improve　the　photocatalytic　H2　generation　activity　of　the　0D/1D　CdS/TiN　heterojunction　over　a　wide　spectral　range.　Furthermore,　owing　to　the　high　metallicity　and　low　work　function,　an　ohmic-junction　was　formed　between　the　CdS　and　TiN,　favoring　the　transfer　of　hot　electrons　generated　from　TiN　nanobelts　the　CdS　nanoparticles,　followed　by　the　reaction　with　water　to　generate　H2.　Consequently,　the　0D/1D　CdS/TiN　heterojunction　demonstrated　H2　generation　activity　even　under　light　irradiation　at　760　nm,　while　the　pure　CdS　and　Pt　nanoparticles　modified　CdS　presented　no　activity.　This　work　opens　a　new　insight　into　coupling　plasmonic　cocatalysts　to　realize　full　spectrum　H2　production.　©　2022
