A water boost for methanol synthesis Model catalysts based on metals and metal oxides can dissociate methane (CH 4 ) at room temperature, converting it directly to 3 OH). Liu et al. show that one of these catalysts, an “inverted” CeO x -Cu 2 O oxide Cu(111), tunes the selectivity from forming CO surface CH groups, as revealed by ambient-pressure x-ray photoelectron spectroscopy. Theoretical modeling showed adsorbed blocks dissociation instead oxidizes reduced catalyst. Hydroxyl groups generate species dissociated , then goes form displace OH gas phase.
