Catalytic Oxidation Processes for Water and Wastewater Treatment

Catalytic Oxidation Processes for Water and Wastewater Treatment

This community develops chemical and catalytic methods to degrade organic pollutants and disinfect water, focusing on the efficient activation of oxidants to remove contaminants from drinking water and wastewater.

The research centers on advanced oxidation processes, specifically the activation of peroxymonosulfate, persulfate, and ozone using catalysts. Key mechanisms involve the generation of reactive oxygen species, including hydroxyl radicals and singlet oxygen, to break down persistent organic matter. Common catalytic materials include cobalt, iron, and manganese oxides, as well as carbon-based supports like activated carbon and biochar. The work frequently addresses the degradation of specific pollutants, such as tetracycline antibiotics and bisphenol A, while also examining the formation of disinfection byproducts from chlorine and peracetic acid treatments.

The largest share of the community's output is found in chlorine research, accounting for 12.5% of all chlorine research, and 2,348 papers here. It also represents 5.0% of bromine research and 3.1% of oxygen research.

The community comprises 14,796 papers, published primarily in the Journal of Water Process Engineering, Chemical Engineering Journal, and Water Research.

Recent work continues to refine catalyst design for selective oxidant generation, with new studies exploring single-atom catalysts, nonradical pathways, and the degradation of emerging contaminants like PFAS and antibiotics.
