The green synthesis of multifunctional ZnO nanoparticles (NPs) was prepared by treatment of zinc nitrate with an extract of Garcinia gummi-gutta seed by the combustion method. The ZnO NPs were characterized by XRD, scanning electron microscopy, UV-visible, FTIR spectroscopic techniques. The prepared ZnO NPs were evaluated for photoluminescence (PL), antioxidant properties and also utilized as a catalyst for the formylation of aromatic amines and biodiesel production. The study reveals that the reaction is simple, mild and environmental friendly. Furthermore, the reaction results in excellent yield of products.
