▎ 摘　　要

Metal-free carbon-based hybrids composed of reduced graphene oxide (rGO) and C3N3S3 polymers with a layered "sandwich" structure were fabricated by an in situ two-step polymerization strategy and used as visible light photocatalysts for selective aerobic oxygenation of benzylic alcohols to the corresponding aldehydes, at good efficiency and high selectivity. This work shows the great potential and prospective application of the metal-free C3N3S3 polymer in the photocatalyzed synthesis of fine chemicals.
