摘要

Graphical abstractDisplay OmittedHighlights?Graphene oxide interface enhances the rate of photochemical reduction of gold ions in water.?The size, shape and morphology of the Au nanocrystals assembled on the RGO nanosheets are controlled by the photochemical reduction process.?Enhanced photothermal energy conversion from the Au@RGO nanocomposites is observed.?The Au@RGO nanocomposites are promising materials for photothermal therapy and for the efficient conversion of solar energy into usable heat for a variety of applications.AbstractA novel photochemical approach is presented for the synthesis of shape-con
