摘      要：Crystal phase engineering on CulnS2(CIS)nanocrystals,especially polytypic structure,has become one of the research hotspots to design the advanced materials and devices for energy conversion and environment ***,the polytypic CIS nanosheets(NSs)including zincblende/wutzite and chalcopyrite/wurtzite types were first time achieved in a hot-injection system using oleic acid and liquid paraffin as the reaction ***-obtained polytypic CIS NSs exhibit significantly enhanced light-absorption abillty and visible-light-driven photocatalytic performance originating from the rational hetero-crystalline interfaces and surface defect states,which efficiently inhibit the recombination of photo-generated ***,the polytypic CIS NSs were spin-coated onto the surface of fluorinated-tin oxide glass substrate and used as the photoelectrode,which shows an excellent photoelectrochemical(PEC)activity in aqueous *** present work not only provides a facile,rapid,low-cost,and environmental-friendly synthesis strategy to design the crystal phase and defect structure of ternary chalcogenides,but also demonstrates the relationships between the polytypic structure and photocatalytic/photoelectrochemical properties.
