Low-temperature deep oxidation of olefins and DME over cobalt ferrite

摘要: Abstract This work reports the facile synthesis of cobalt ferrite catalysts by pulsed spray evaporation chemical vapor deposition (PSE-CVD) for low-temperature oxidation dimethyl ether and olefin exhaust emission. To better understand structure–performance relationship, prepared thin films were comprehensively characterized in terms phases, surfaces redox properties. A well-crystallized inverse spinel structure was revealed both XRD Raman analyses. Helium ion microscopy (HIM) images show that obtained have cauliflower with apparent open porosity. The catalytic performance as-prepared evaluated a fixed-bed quartz reactor–FTIR system. results indicate ferrites very active total propene, n -butene DME at low temperature no CO observed during processes. attractive is attributed to mechanism which involves synergistic effect morphology, reducibility, lattice oxygen mobility.
