Abstract
A broad range of ZrO2 loadings on silica were found to be effective in stabilizing SiO2 against sintering. The combination of La2O3 and ZrO2 on SiO2 was most effective in stabilizing platinum against sintering in an oxidizing environment. This catalyst is a promising candidate fo r improved sulfuric acid catalyst since platinum and SiO2 have both be en stabilized.
