High Catalytic Performance of Ruthenium‐Doped Mesoporous Nickel–Aluminum Oxides for Selective CO Methanation

Abstract

Deep-cleaned hydrogen can be made available for fuel cells in one step. 1 vol % CO contained in hydrogen was removed to levels of less than 10 ppm over ruthenium-doped mesoporous Ni-Al oxides (see picture) by selective CO methanation, with a working temperature window greater than 50 °C that included the 200–250 °C range. The catalysts exhibited excellent long-term stability. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
