摘要

Abstract

Ce-Zr solid solution (Ce

CZO) was prepared by the citric acid sol-gel method. The CZO was then used as a support for Pd/CZO catalysts for the oxidative carbonylation of phenol to diphenyl carbonate. The Pd/CZO catalyst showed enhanced activity and diphenyl carbonate selectivity compared with the Pd/CeO

catalyst. The catalytic performance of Pd/CZO was influenced by the calcination temperature of the CZO support. X-ray diffraction

scanning electron microscopy

adsorption-desorption measurements

X-ray photoelectron spectroscopy and H

temperature-programmed reduction measurements were used to investigate the effects of Zr doping and calcination temperature. The catalytic performance of Pd/CZO and Pd/CeO

for the oxidative carbonylation of phenol was affected by several factors

including the specific surface area

and/or oxygen vacancy content

oxygen species type and Pd(II) content of the catalyst. All these properties were influenced by Zr doping and the calcination temperature of the CZO support.
