Abstract

The Mo/SnO2 catalyst was prepared by the impregnation method and characterized by thermal analysis, X-ray diffractometry, diffuse reflectance infrared (DRIFT) spectroscopy as well as N2 adsorption/desorption (BET method) techniques. The results permit to infer that the highly dispersed Mo ions strongly affect SnO2 crystallization forming only MoO 3 and SnO2 phases. Moreover, the thermal behavior of Mo/SnO2 showed the dissolution of MoO3 in SnO2 crystals at temperatures above 750°C. Nevertheless, reduced MoO 3/SnO2 presented marked activity and selectivity towards CH4 decomposition at 700°C so as to forming a formaldehyde intermediate but rather favored the formation of CO2.
