A　strategy　that　visible-light　responsive　zeolitic-imidazolate-framework-67　(　ZIF-67)　encapsulates　noblemetal　sensitized　semiconductors,　ZnO@M　(　M　=　Au,　Pt,　and　Ag)　to　fabricate　composite　catalysts　for　photoelectrochemical　(PEC)　water　splitting　is　proposed.　The　obtained　ZnO@M@ZIF-67　catalysts　have　good　catalytic　performance,　particularly,　the　ZnO@Au@ZIF-67　exhibits　quite　improved　photoconversion　efficiency　and　photocurrent　density,　superior　to　most　of　the　reported　photoelectrode　catalysts.　This　can　be　attributed　to　the　wider　solar　spectra　harvesting　capability　originating　from　visible-light　responsive　ZIF67　and　UV-light　active　ZnO.　Simultaneously,　their　integration　enables　interfacial　electrons　in　the　ZIF-67　shell　to　easily　transfer　to　the　ZnO@Au　core,　providing　good　electron-hole　separation.　In　addition,　the　porous　ZIF-67　as　a　protective　shell　ensures　structural　robustness,　while　maintaining　fast　ion　or　gas　bubble　diffusion　through　its　pores,　accounting　for　stable　and　excellent　PEC　performance.
