An　efficient　MoO2/CdS　photocatalyst　has　been　successfully　constructed　by　a　relatively　facile　way　to　construct　a　specific　combination　mode　through　chemical　bond,　which　results　in　strong　interaction　between　MoO2　nanoparticles　and　CdS　nanorods.　X-ray　photoelectron　spectroscopy　further　confirms　the　formation　of　Mo–S　bonding,　which　acts　as　a　connection　bridge　and　develops　an　intimate　contact　between　CdS-NRs　and　MoO2　nanoparticles.　Benefitting　from　the　synergic　effect　of　the　enhancement　on　the　light　absorption,　carriers’　efficient　separation　and　lower　the　overpotential　of　hydrogen　evolution,　the　obtained　MoO2/CdS　composite　has　shown　an　excellent　enhancement　in　photocatalytic　H2　generation　and　the　optimal　H2　evolution　rate　reaches　as　high　as　30　times　than　that　of　pure　CdS　nanorods.　We　have　experimentally　shed　light　on　the　mechanism　of　this　excellent　enhancement　performance　in　detail.　Moreover,　our　work　can　broaden　the　construction　and　the　application　of　developing　other　efficient　photocatalytic　material　containing　transition　metal　oxide.　©　2019　Hydrogen　Energy　Publications　LLC
