Silver Iodide Nanospheres Wrapped in Reduced Graphene Oxide for Enhanced Photocatalysis

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, Rhodamine B (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.
