Abstract: Evolution of the IRAS spectrum with temperature after adsorbing methanol at room temperature. The bands at 2930 and 2820 cm21 are due to the methoxy species C –H stretches, while that at 2870 is due to the formate. Here, we report a simple, quantitative model to describe the behaviour of bi-cationic oxide catalysts, in terms of selectivity variation as a function of increased loading of one cation into a sample of the other. We consider its application to a particular catalytic system, namely the selective oxidation of methanol, which proceeds with three main C1 products, namely CO2, CO, and H2CO. The product selectivity varies in this order as Mo is added in increasing amounts to an iron oxide cata
