▎ 摘　　要

Reduced graphene oxide (rGO) was synthesized and impregnated with silver and silver/copper for in situ DRIFTS investigation of ethylene oxidation. The catalysts were characterized using different techniques. SEM micrographs showed that the metals are dispersed on the rGO surface. XPS results showed the presence of the metallic silver and copper as CuO and Cu2O oxides. The in situ DRIFTS showed that in both catalysts the total oxidation of ethylene reaction prevails besides the intermediate formation of acetaldehyde. The presence of Cu ions or CuO and Cu2O at the surface indicate the presence of electronic structure, which may enhance the oxidation reaction. [GRAPHICS]
