A　novel　and　highly　efficient　photocatalyst　MoS2/UiO-66/CdS　has　been　fabricated　through　dual　modification　of　CdS　with　metal-organic　framework　(MOF)　UiO-66　and　MoS2.　UiO-66　was　firstly　introduced　as　a　matrix　for　the　well-dispersed　growth　of　CdS,　resulting　in　large　active　surface　area.　Moreover,　the　heterojunction　between　UiO-66　and　CdS　promoted　the　separation　of　photogenerated　electron-hole　pairs.　MoS2　as　cocatalyst　was　further　deposited　on　UiO-66/CdS　via　a　facile　photo-assisted　approach.　This　technique　made　CdS,　UiO-66　and　MoS2　undergo　an　intimate　interfacial　interaction,　setting　a　stage　for　rapid　transfer　of　photogenerated　electrons　between　the　components　of　the　composite,　and　hence　dramatically　increased　the　synergetic　catalytic　effect　of　UiO-66,　MoS2　and　CdS.　Without　a　noble-metal　cocatalyst,　the　obtained　MoS2/UiO-66/CdS　composites　functioned　as　high-performance　photocatalysts　for　H2　evolution　under　visible　light　irradiation.　An　unusual　H2　production　rate　of　650μmolh-1　has　been　reached　by　the　sample　of　MoS2/UiO-66/CdS　when　the　content　of　UiO-66　is　50wt%　and　MoS2　is　1.5wt%.　This　is　nearly　60　times　higher　than　the　H2　evolution　rate　with　pure　CdS　and　also　exceeds　that　of　Pt/UiO-66/CdS　under　the　same　reaction　conditions.　More　importantly,　in　sharp　contrast　with　the　obvious　deterioration　in　photoactivity　of　pure　CdS,　the　MoS2/UiO-66/CdS　displayed　significantly　enhanced　photostability.　This　study　clearly　demonstrates　the　benefit　of　using　MOFs　as　ideal　support　and　MoS2　as　cocatalyst　to　work　cooperatively　for　enhancing　the　photocatalytic　H2　evolution　activity　and　stability　of　semiconductors.　©　2014　Elsevier　B.V.
