Review and Perspectives of Enhancement in the Catalytic Stability for the Complete Combustion of CO, CH4, and Volatile Organic Compounds

Abstract

As typical air pollutants, CO, CH4, and volatile organic compounds (VOCs) have received great attention due to their negative impact on the environment and human health. Heterogeneous catalysts are widely used in the catalytic removal of exhaust emission from industrial and automobile sources but still suffer from deactivation because of various factors. The development of a catalyst with excellent catalytic stability is highly desired. We herein summarized the recent progress for enhancing the catalytic stability of catalysts and tried to obtain an in-depth understanding of the long-term durability, resistance to sinter, and tolerance for multi-impurities. Finally, the current challenges and future perspectives for developing stable and highly efficient catalysts in the fields of synergistic catalytic removal of pollutants or resource utilization of VOCs via the selective catalytic oxidation are proposed.
