CuZn/ZrO2 catalytic honeycombs for dimethyl ether steam reforming and autothermal reforming

► CuZn/ZrO2 catalytic monoliths perform excellent for DME steam reforming. ► The best selectivity to H2 and CO2 is exhibited by a catalyst with a Cu:Zn molar ratio of 1:10. ► SEM and XPS show that better Cu dispersion is attained by increasing Zn/Cu ratio. ► CuZn/ZrO2 catalysts deactivate under DME autothermal reforming due to the prevalence of methoxy species.
