Zeolitic imidazolate framework‐67 (ZIF‐67) functionalized with graphene quantum dots was prepared and utilized for the reduction of Au (III) stabilization nanoparticles. This newly ZIF‐67/GQD@Au characterized different techniques employed as a capable heterogeneous catalyst aromatic nitro compounds A 1 ‐coupling reaction alkynes, amines, aldehydes in water solvent. Experiments indicate that this is able to reduce nitroarenes short times (10–20 min) at room temperature corresponding amines were obtained excellent yields (90–100%). Also, reactions structurally presence proceed effectively 60°C desired propargylic amine achieved good very (76–88%) during day. displayed stability recyclability both recycled six runs small decrease activity.
