Deep Oxidation Removal of Nitric Oxide and SO<sub>2</sub> via Singlet Oxygen and Hydroxyl Radicals in the LaCoO<sub>3‑δ</sub>/H<sub>2</sub>O<sub>2</sub> System.
Ontology highlight
ABSTRACT: This study proposes a novel LaCoO3‑δ/H2O2 Fenton-like process for the efficient generation of nonradical singlet oxygen (1O2) and hydroxyl radicals (•OH), enabling the deep oxidation of nitric oxide (NO), as well as simultaneous denitrification and desulfurization. A LaCoO3‑δ perovskite material enriched with Co3+ ions and oxygen vacancies (OV) was successfully synthesized by using a one-step citric acid sol-gel method. OV enhances electron mobility and expedites the redox cycling of surface Co2+/Co3+ pairs, thereby promoting the generation of •OH and •O2 -. The high Co3+ content further facilitates the transformation of •
