Ceria-Based Catalysts for Environmental Remediation and Wound Healing
This research community develops cerium oxide nanoparticles and related metal oxide catalysts to treat environmental pollutants and accelerate the healing of chronic wounds, particularly diabetic ulcers.
The work centers on the synthesis and surface modification of ceria (CeO2) nanoparticles, often combined with gold, platinum, or manganese oxides. In environmental applications, these materials are engineered for selective catalytic reduction of nitrogen oxides, oxidation of volatile organic compounds like toluene, and the water-gas shift reaction. In biomedical applications, the same catalytic properties are leveraged to scavenge reactive oxygen species, manage oxidative stress, and deliver therapeutic agents via hydrogel dressings. The recurring focus is on tuning oxygen vacancy concentrations to enhance catalytic activity for both pollutant removal and tissue repair.
The largest share of this community's output is found in cerium research, accounting for 26.0% of all cerium research tracked, with 10,867 papers. This is the element with the highest paper count within the group.
The community comprises 43,330 papers, publishing most frequently in Applied Catalysis B: Environmental, Journal of Catalysis, and Catalysis Today.
Recent work continues to focus on multifunctional hydrogel platforms for diabetic wound repair and the engineering of oxygen vacancies in ceria for photocatalysis and antibacterial action.
