Abstract

Sulfated TiO2 was more active and deactivated more slowly than Degussa P-25 TiO2 during PCO of acetaldehyde above 373 K. Thermal catalytic reactions appear to poison both catalysts. Sulfating TiO2 increased surface area by 60% and increased the number of acetaldehyde adsorption sites by a factor of 1.7.
