Abstract
Novel Pd-Sn bimetallic nanoparticles have been synthesized using the wet chemical technique. The nanoparticles show excellent catalytic activity in oxidizing secondary benzyl alcohol to the corresponding carbonyl in water as the solvent without any additive. It also withstood multiple cycles without loss of activity. Preliminary kinetic studies indicate a β-hydride elimination mechanism.
Graphical abstract
A bench-friendly wet-chemical method is designed to synthesize Pd-Sn bimetallic nanoalloys characterized by PXRD, FESEM, HRTEM, UV-Vis, FT-IR, EDAX, and ICP-OES. The nanoalloy is highly dispersible in water and catalyzes the oxidation of secondary alcohols in water with high TOF.
