Abstract
Abstract Hexamethyldisiloxane (HMDSO) is one of the most serious poisons in the field of catalysts. In this research, the deactivation of SnO2 and Pd/SnO2 catalysts by HMDSO was studied. Surface modification with Ag/Al2O3 was used to improve the resistance of the catalyst to HMDSO deactivation. To intrinsically investigate the deactivation mechanism of the catalyst, the morphology, structure and surface state of the catalyst were characterized by SEM, EDS, HRTEM, XPS, Raman, and PL. HMDSO decomposed on the SnO2 catalyst surface, yielding organosilicon and silicates (SixOy, y/x
