Dramatic Effects of Gallium Promotion on Methanol Steam Reforming Cu-ZnO Catalyst for Hydrogen Production: Formation of 5 angstrom Copper Clusters from Cu-ZnGaOx

Abstract:

A new class of copper, zinc, and gallium mixed oxides (CuZnGaOx) with different chemical compositions obtained by a coprecipitation technique is identified as a highly active catalyst for the low-temperature, direct steam reforming of methanol to supply hydrogen gas to portable fuel cell devices. Their catalytic activity and selectivity are found to be critically dependent on the copper surface area, catalyst structure, and metal-support interaction, etc. As a result, temperature-programmed r...
