A novel Zn–Al spinel-alumina composite supported gold catalyst for efficient CO oxidation†
Abstract
A spinel-alumina inert oxide supported gold catalyst with high Au dispersion and excellent CO oxidation activity was developed by a deposition–precipitation method. The activation atmosphere could tune the reaction pathway by adjusting the amount of surface adsorbed water species, thus transforming the reaction intermediates from HCO3− or CO32− to COOH.
