Catalytic Activation of Sulfate Radicals and Singlet Oxygen for Water Purification
This community develops catalytic systems that activate oxidants like peroxymonosulfate and hydrogen peroxide to degrade organic pollutants in wastewater and drinking water.
The work centers on designing heterogeneous catalysts—often based on iron, cobalt, or carbon structures—to trigger advanced oxidation processes. Recurring themes include the activation of peroxymonosulfate and persulfate, the generation of reactive oxygen species such as singlet oxygen and hydroxyl radicals, and the specific degradation of persistent contaminants like tetracycline antibiotics and methylene blue dyes. Researchers frequently investigate the underlying electron transfer mechanisms and the balance between radical and non-radical pathways to enhance the efficiency of pollutant removal in aqueous solutions.
The community is most prominent in research tracked for Iron, representing 1.0% of all Iron-related papers in this dataset, and Oxygen, representing 1.0% of Oxygen-related papers. It also constitutes a significant share of Cobalt research, accounting for 1.0% of that element's tracked output.
The community comprises 21,120 papers, with the highest publication volumes in the Chemical Engineering Journal, Separation and Purification Technology, and the Journal of Water Process Engineering.
Recent work continues to focus on refining single-atom catalysts and metal-organic frameworks to optimize electron transfer and non-radical oxidation pathways, with specific applications in removing antibiotics, pesticides, and industrial dyes from water streams.
