Ceria-Based Catalysts for Low-Temperature Oxidation of Volatile Organic Compounds and Hydrocarbons
This research community focuses on the design and mechanism of oxide catalysts, primarily cerium dioxide (ceria), to facilitate the low-temperature oxidation of pollutants such as toluene, methane, and carbon monoxide.
The work centers on engineering oxygen vacancies and metal-support interactions within ceria and mixed-metal oxide structures to enhance catalytic activity. Recurring themes include the oxidation of toluene and other volatile organic compounds (VOCs), the water-gas shift reaction, and methane combustion. Researchers frequently investigate how doping with platinum, palladium, or manganese, and the creation of specific defect sites, allows these catalysts to operate efficiently at room temperature or low temperatures. The materials studied range from ceria nanoparticles and spinel oxides to supported single-atom catalysts, with a strong emphasis on understanding the role of lattice oxygen and surface defects in the reaction mechanism.
The largest share of this community's output is found in cerium research, accounting for 15.5% of all tracked cerium papers, with 12,864 papers in this group. It also represents a significant portion of platinum (1.8%) and palladium (1.9%) research, reflecting the common use of these noble metals as active sites supported on ceria.
The community comprises 37,858 papers, with the most frequent publications appearing in Applied Catalysis B: Environmental, Journal of Catalysis, and Catalysis Today.
Recent work continues to explore the modulation of metal-support interactions and defect engineering in ceria and spinel oxides. Current studies focus on enhancing the degradation of volatile organic compounds and improving low-temperature oxidation of hydrocarbons through precise control of oxygen vacancies and electronic structures in catalysts such as Pt/CeO2 and Co-based oxides.
