    Co3O4 Catalysts on CeO2-ZrO2 Supports and Co3O4-CeO2 Catalysts on Al2O3/SiO2 Supports for the Oxidation of Propylene by Tien The Nguyen, Phuong Thi Mai Pham, Thang Minh Le, Isabel Van Driessche

    Published 2015-01-01
    “…Catalytic activities of mixed Co3O4-CeO2 with different loading contents supported on high surface area supports (Al2O3, SiO2) were then measured. The optimal composition of active phase was still 30 wt% but the minimum temperature of the highest activity increased to above 300°C due to the inert nature influence of the support.…”
