Oxide Catalysts for Low-Temperature NOx Reduction and VOC Oxidation
This community develops oxide-based catalysts to convert harmful exhaust gases, such as nitrogen oxides and volatile organic compounds, into harmless substances at low temperatures.
The research focuses heavily on ceria-based materials, manganese oxides, and titanium dioxide supports to facilitate selective catalytic reduction of NOx with ammonia and the catalytic oxidation of toluene, methane, and other volatile organic compounds. A central theme is the engineering of oxygen vacancies and surface defects to enhance reactivity and stability. Applications include flue gas treatment, catalytic converters, and the removal of toxic emissions from industrial and automotive sources. The work emphasizes mechanism understanding, synthesis of supported catalysts, and optimizing performance under humid or low-temperature conditions.
The largest share of the community's output is found in cerium research, representing 9.5% of all cerium research tracked, with 7,149 papers in this group. Manganese research also shows a significant concentration, accounting for 1.8% of manganese research with 2,401 papers.
The community comprises 31,387 papers, publishing primarily in Applied Catalysis B: Environmental, Catalysis Today, and the Journal of Catalysis.
Recent work continues to explore the role of oxygen vacancies and metal-support interactions in cobalt, ceria, and platinum-based systems for the oxidation of benzene, furfural, and exhaust gases, with specific attention to sulfur tolerance and low-temperature performance.
