Double-Shell and Flower-Like ZnS-C3N4 Derived from in Situ Supramolecular Self-Assembly for Selective Aerobic Oxidation of Amines to Imines

Multishelled micro-/nanostructures have attracted much research attention because of their unique properties. It is a big challenge to fabricate multishelled hollow structures of complex nanoarchitectures with the respective shells different in composition. Herein, the double-shell and flower-like ZnS-C3N4 (2-ZSCN) was fabricated by a facile supramolecular self-assembly method. Because of its unique structure, 2-ZSCN exhibits enhanced photocatalytic activity and stability in the selective aerobic oxidation of amines to imines under visible-light irradiation.
