摘要：

Several novel silver-silica catalysts were prepared by means of sol-gel method, which exhibited high activity and selectivity in the catalytic oxidation of methanol to formaldehyde. The optimum content of silver was determined as 20%(w/w.), which showed 97% conversion and 85.5% yield of formaldehyde. Some other superiority of the as-prepared silver catalysts was observed by comparing with the commercial silver catalysts, including pumice-supported silver and electrolytic silver. XRD patterns reveal that silver is present as a crystalline state in the Ag-SiO2 catalysts.
