Conventionally, Pd catalysis has been widely used in either heterogeneous or homogeneous thermocatalytic organic synthesis. Herein, we demonstrate a case study on the important, cocatalyst role of Pd nanoparticles in ternary In 2 S 3 –(reduced graphene oxide–palladium) [In 2 S 3 –(RGO–Pd)] composites for the selective oxidation of alcohols under visible‐light irradiation. Pd acts as dual cocatalyst along with RGO to promote the more efficient separation of photogenerated electron–hole pairs and facilitate their spatial transfer across the interface in ternary In 2 S 3 –(RGO–Pd) composites, which leads to higher activity than that of binary In 2 S 3 –RGO composites. This work highlights the promising scope of using Pd nanoparticles as a cocatalyst for promoting visible‐light photocatalysis towards selective organic transformations under ambient conditions.
