Investigating the performance of CoxOy/activated carbon catalysts for ethyl acetate catalytic combustion

Abstract The catalytic properties of Co-supported activated carbon (AC) catalysts for ethyl acetate catalytic elimination in air were investigated. Results showed that air atmosphere promoted the generation of high-valence state cobalt oxides, and promote the production of reactive oxygen species (ROS) in the Co 3 O 4 /AC catalyst. ROS crucially functioned in improving the catalytic activity of Co 3 O 4 /AC catalysts. Therefore, CoACA catalyst prepared in air exhibited higher catalytic activity than CoACN catalyst prepared in nitrogen, and CoACA catalyst led to high ethyl acetate conversion (>93%) and stability at a low reaction temperature (210 °C).
