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.

Enhanced hydrogen evolution and symmetric supercapacitor performance of a Ru-doped multiphase WS2 electrode

“…4a) and and 66 W h kg −1 ) electrodes. The supercapacitor performance of the 2H@1T multiphase Ru doped WS 2 electrode is close to the literature report of 2D TMD based symmetric or asymmetric supercapacitor cells [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] (Table 1).…”

In Situ Reconstruction of Active Heterointerface for Hydrocarbon Combustion through Thermal Aging over Strontium-Modified Co3O4 Nanocatalyst with Good Sintering Resistance

“…Metal and metal complex nanocatalysts have found extensive applications across various fields, including environmental protection as catalytic degraders and fuel cells for efficient cleaning. − Despite their numerous benefits, these catalysts with nanoscale generally encounter a significant obstacle in the form of sintering issue under high-temperature condition along with long-term working, which impedes their further practical applications. The process of thermally or chemically induced sintering causes smaller metal/oxide nanoparticles to merge into larger ones, resulting in catalyst instability and substantial deactivation that severely hampers their overall efficiency. − Consequently, the development of nanocatalysts with exceptional low-temperature activity and remarkable resistance to sintering holds immense economic and scientific significance.…”

Cobalt–Magnesium Oxide Catalysts for Deep Oxidation of Hydrocarbons

“…Methods based on the use of various catalytically active compositions are widely used in the purification of industrial gases from various organic products (methane and other hydrocarbons, carbon monoxide, soot, benzopyrene, aldehydes, etc.) [1][2][3][4]. Noble metals (Pt, Pd, Rh), as well as compositions based on metal oxides of variable valence, exhibit high activity in deep oxidation reactions.…”

“…The high mobility of lattice oxygen in systems containing Co 3+ puts them on a par with catalysts based on noble metals in terms of specific activity [6]. The low cost of cobalt-oxide-based systems compared to scarce noble metals makes these catalysts especially promising [1][2][3][4].…”
