▎ 摘　　要

We have prepared nanocomposites of well-defined spherical AgI nanostructures wrapped in reduced graphene oxide nanosheets (AgI@RGO). The as-obtained AgI@RGO nanocomposites exhibit an enhanced photocatalytic activity and stability in the degradation of organic pollutants, namely, RhodamineB (RhB), in comparison with bare AgI nanospheres. The hybridization of AgI nanospheres with RGO nanosheets affords a good adsorptive capacity for RhB molecules, facilitated charge transfer, and suppressed recombination of electron-hole pairs. These figures of merit lead to an enhanced photocatalytic performance over AgI@RGO. This work opens new possibilities for the development of highly efficient and stable visible-light-driven composite photocatalysts for environmental purification.
