Abstract:

We fabricated porous copper(PC) by dealloying Al from Cu-Al alloy and obtained M/PC(M=Ag, Au, Pt, Pd) through galvanic replacement of Cu with noble metals using PC as reductant and template. The structural and chemical properties of the samples were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM) with energy-dispersive X-ray spectroscopy(EDS). The catalytic performance of PC and M/PC for gas-phase selective oxidation of benzyl alcohol was investigated. PC-based M/PC catalysts showed relatively high catalytic activity in oxidation of benzyl alcohol at high temperature, among which 1% Ag/PC had the best catalytic properties.
