Zeolite MCM-22 Modified with Au and Cu for Catalytic Total Oxidation of Methanol and Carbon Monoxide
Original language description
The goal of this work was to use MCM-22 zeolites for preparation of monometallic (Cu or Au) and bimetallic (Cu and Au) catalysts for oxidation reactions. The focus was on precise determination of the nature of gold and copper species and their activity in the oxidation processes. For that purpose several characterization techniques were applied (XRD, N2 adsorption/desorption, TEM, SEM, UV-vis, H2-TPR, 27Al MAS NMR, FT-IR with the adsorption of pyridine, NO, and CO, ESR spectroscopy). They allowed us todefine the following species formed on MCM-22 surface: metallic gold particles (XRD, UV-vis), isolated Cu2+ with octahedral coordination (UV-vis, ESR), square planar Cu2+ cations (ESR, IR), Cu+ species (ESR+NO, FTIR+CO, and FTIR+NO), and oligonuclear clusters (UV-vis) as well as CuO-like species (H2-TPR). The presence of gold on the MCM-22 surface modified further by copper species caused the interaction between two modifiers leading to much easier reduction of CuO-like species and highe
