A series of catalysts was prepared with SnO2: h-MoO3 molar ratio 1:1; 1:2.3; 2.3:1 and 5.7:1. The catalysts were characterized by various techniques including X-ray phase, X-ray diffraction (XRD) and synchronous thermal analysis, scanning electron microscopy (SEM), BET method. An important effect of the introduction of molybdenum atoms into the structure of SnO2 was lattice defect. Heat treatment of the mechanically activated mixture at a temperature of 600–750  resulted in obtaining crystalline Sn(MoO4)2. The catalytic activity of the samples was investigated by the oxidative dehydrogenation of methanol. The results reported that varying the SnO2:MoO3 ratio allows adjusting the selectivity of the methanol conversion process over methyl formate and dimethyl ether.
