Abstract We report an easy method of using SiO 2 as the support and HAuCl 4 as the precursor for synthesizing a Au/CoO x /SiO 2 catalyst that is highly active in low-temperature CO oxidation. The surface of SiO 2 was modified with a small amount of highly dispersed CoO x (6 wt%) before the loading of gold. A 78% conversion of CO was achieved at room temperature and 100% at temperatures above 333 K over the Au/CoO x /SiO 2 catalyst in CO oxidation. Compared with Au/SiO 2 , the existence of CoO x… CONTINUE READING
