- Abstract
The main reactions yielding hydrogen are the recombination of hydrogen atoms on copper clusters and methyl formate decomposition. Methyl formate results from the interaction between the linear methoxy group and the formate complex located on CuO. The source of CO appearing in the gas phase is the formate complex, and the source of CO is methyl formate. The rates of methoxy group conversion and product formation over supports (ZrO, CeO, CeZrO) and copper-containing catalysts (5%Cu/CeO, 5%Cu/ZrO, 2%Cu/CeZrO, 2%Cu/CeYZr) are compared. The dominant process in methoxy group conversion over the supports and copper-containing catalysts is methanol decomposition to H and CO and to H and CO, respectively. The methoxy group conversion rate is proportional to the H and CO formation rate and is determined by the concentration of supported copper.
