Ce-Zr solid solution (CexZr1-xO2, 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 di-Ph carbonate. The Pd/CZO catalyst showed enhanced activity and di-Ph carbonate selectivity compared with the Pd/CeO2 catalyst. The catalytic performance of Pd/CZO was influenced by the calcination temperature of the CZO support. X-ray diffraction, SEM, N2 adsorption-desorption measurements, XPS and H2 temperature-programmed reduction measurements were used to investigate the effects of Zr doping and calcination temperature The catalytic performance of Pd/CZO and Pd/CeO2 for the oxidative carbonylation of phenol was affected by several factors, including the sp. surface area, Ce3+ 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. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0COA of Formula: C13H10O3).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C13H10O3
