Effect of tin and potassium addition on the nature of platinum supported on silica

This study aimed to examine the effects of tin and potassium addition on the catalytic properties of Pt/SiO2. Temperature programmed reduction (TPR), UV-vis spectroscopy by diffuse reflectance (DRS) and CO chemisorption were used to characterize these catalysts. The activity of the catalyst was determined by the isobutane dehydrogenation .
