Ceria-Based Catalysts for Oxidation, Reduction, and Environmental Remediation
This community focuses on the design and application of cerium oxide (ceria) and mixed-metal oxide catalysts to drive selective oxidation and reduction reactions, primarily for removing pollutants from industrial exhaust and treating water.
The work centers on engineering the surface of ceria nanoparticles and manganese oxide composites to optimize oxygen vacancy formation and redox cycling. Recurring applications include the catalytic reduction of nitrogen oxides, the selective oxidation of volatile organic compounds like toluene, and the water-gas shift reaction for hydrogen production. Researchers also investigate the mechanical polishing of oxide surfaces and the use of these materials as nanozymes for scavenging reactive oxygen species in biological contexts. The emphasis is on enhancing catalytic activity through defect engineering and strong metal-support interactions.
The largest share of the community's output is found in cerium research, accounting for 37.4% of all cerium research, and 8,270 papers here. Manganese and platinum also contribute significantly, representing 4.1% and 3.2% of their respective elemental research totals.
The community comprises 25,739 papers, published most frequently in Applied Catalysis B: Environmental, Journal of Catalysis, and Chemical Engineering Journal.
Recent work continues to explore defect-engineered ceria for photocatalysis and antibacterial action, as well as dynamic current-tuned catalysts for methane oxidation and low-temperature CO oxidation.
