Enabling High Activity Catalyst Co₃O₄@CeO₂ for Propane Catalytic Oxidation via Inverse Loading.

ABSTRACT: Propane catalytic oxidation is an important industrial chemical process. However, poor activity is frequently observed for stable C-H bonds, especially for non-noble catalysts in low temperature. Herein, we reported a controlled synthesis of catalyst Co₃O₄@CeO₂-IE via inverse loading and proposed a strategy of oxygen vacancy for its high catalytic oxidation activity, achieving better performance than traditional supported catalyst Co₃O₄/CeO₂-IM, i.e., the T₅₀ (temperature at 50% propane conversion) of 217 °C vs. 235 °C and T₉₀ (temperature at 90% propane conversion) of 268 °C vs. 348 °C at the propane space velocity of 60,000 mL g^-1 h^-1. Further investigations indicate that there a
