The selective oxidation of ethylene glycol and 1,2-propanediol on Au, Pd, and Au–Pd bimetallic catalysts
Abstract The oxidation of ethylene glycol (HOCH 2 CH 2 OH) and 1,2-propanediol (HOCH(CH 3 )CH 2 OH) was investigated over Pd/C, Au/C, and a series of bimetallic catalysts prepared by electrolessExpand
