Nanosized silver bromide: an efficient catalyst for alcohol oxidation in the presence of a multinuclear silver complex

Abstract

Upon investigating a silver-based complex for the alcohol oxidation reaction, we found AgBr as a new and efficient catalyst for the reaction in the presence of oxone (2KHSO₅·KHSO₄·K₂SO₄). The catalyst was characterized by scanning electron microscopy, energy dispersive spectrometry, transmission electron microscopy, dynamic light scattering, X-ray diffraction, chronoamperometry, X-ray photoelectron spectroscopy, and liquid chromatography-electrospray ionization mass spectrometry. We propose that nanosized silver bromide can be used as a catalyst for the oxidation of alcohol to aldehyde in the presence of oxone (2KHSO₅·KHSO₄·K₂SO₄) as an oxidant.
