Effect of SiOH/Ag ratio on catalytic activity of Ag/SBA-15 catalysts in CO oxidation reaction
The effect of the pretreatment temperature of the SBA-15 support on the catalytic activity of Ag / SBA-15 catalysts was studied in the CO oxidation reaction. The catalysts were prepared by incipient wetness impregnation. The supports were preliminarily calcined at 500, 700, and 900 <sup>o</sup>C. The catalysts and supports were investigated by low-temperature nitrogen adsorption, TPD-HO, TPR-H<sub>2</sub> and were tested in the CO oxidation reaction. It was found that the calcination temperature of the SBA-15 support affects the nature of the distribution ofsilver and the catalytic activity of the catalysts.
