Reaction of Nitrate Radicals and DMPO in Non‐Aqueous Media: A Novel Detection Tool to Highlight the Nitrate Radical Role in Photocatalytic Processes

Year: 2025

Type: article

Abstract: The reaction of DMPO as the spin trapping agent with nitrate radicals photocatalytically generated results in the formation of DMPOX showing a highly specific EPR spectrum. The method can be used as a semi‐quantitative and convenient way to detect nitrate radicals in non‐aqueous solutions/suspensions, which was never achieved up to now through EPR spectroscopy. Results support in a more direct way the proposed generation and reactivity of nitrate radicals in photocatalytic media and open a new chapter in the field of heterogeneous photocatalysis.
