Enhanced photocatalytic H2 production from glycerol solution over ZnO/ZnS core/shell nanorods prepared by a low temperature route

► A new water bath route was developed to synthetize ZnO/ZnS core/shell nanorods. ► Those core/shell nanorods were used for photocatalytic H2 evolution. ► Glycerol as sacrificial reagent. ► Thickness of ZnS shell affect the photocatalytic performance.
