Abstract
Photo-stability of surface chromate species (Cr(VI)Ox,surf) on Phillips catalysts isothermally prepared from PCP120 precursor at various temperatures between 200 and 800 °C was investigated by high resolution XPS method. The photo-stability of Cr(VI)Ox,surf was found to be significantly dependent on the calcination temperature for preparation of the catalysts. A correlation between the photo-stability of surface chromate species and the calcination temperatures has been successfully established.
