The　conversion　of　solar　energy　in　a　wide　spectrum　region　to　clean　fuel,　H-2,　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　H-2　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　H-2.　Consequently,　the　0D/1D　CdS/TiN　heterojunction　demonstrated　H-2　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　H-2　production.　(C)　2022　Published　by　Elsevier　Ltd　on　behalf　of　The　editorial　office　of　Journal　of　Materials　Science　&　Technology.
