Formate species (HCOO-) have been suggested as intermediates or spectators in chemical reactions of industrial relevance, such as the water-gas-shift and the methanol steam reforming reaction. Several catalysts, some of them based on ceria, have been proposed to improve the performance of these reactions. One of the main reasons for choosing ceria is its intrinsic redox properties, but only few works describe the formate formation under the oxidizing/reducing environment [2,3], usually modulated by the reaction itself. In this work, we have studied the stability of formate groups in the CH3OH/CeO2 system.
