Research progress on cobalt oxide-based catalysts for catalytic combustion of CVOCs

Research progress in the catalytic combustion of chlorinated volatile organic compounds (CVOCs) on cobalt oxide-based catalysts was summarized briefly in recent years．Three strategies were introduced in detail to improve the activity，stability，and the selectivity of products with environmental acceptable over cobalt oxide-based catalysts，including loading on the supports with acidic properties，loading high Deacon reaction active components，synthesizing cobalt oxide-based mixed oxides for the catalytic combustion of CVOCs．From the perspective of catalyst design, the construction of cobalt oxide-based catalysts with excellent low-temperature redox properties and suitable acid properties is the focus of ongoing research． From the perspective of catalytic technology，coupling a variety of reaction scenarios using multi-field synergy strategy can be selected to improve the low temperature activity，stability and versatility of cobalt oxide-based catalysts． © 2022 Huazhong University of Science and Technology.
