Defective TiOx spontaneously triggers the hydrogenation activity of silver

Abstract

The reactive metal–support interaction (RMSI) between Ag and defective TiO_x spontaneously triggers the selective silver-catalyzed hydrogenation of dimethyl oxalate to methyl glycolate, enabling a >5-fold increase in TOF without prereduction. Importantly, TiO_x confers remarkable oxidation resistance to the metallic Ag phase.
