Extended study of ammonia conversion to N₂ using a Ru/0.2TiZrO₄ catalyst via catalytic wet air oxidation

Abstract

During the (NH4)2SO4 degradation, both the NO2− and NO3− generated can react with NH4+ in the solution and produce N2 as the only final product.

Recent Progress and Prospects in Catalytic Water Treatment

“…Indeed, the formation of nitrogen from catalytic wet oxidation of ammonia on Ru/TiO 2 has been predominantly ascribed to a reaction in aqueous phase between NO 2 – /NO 3 – and NH 4 + according to steps and . Such steps have been further confirmed in slightly acidic conditions: As a matter of fact, it was recently found that step at the surface of the catalyst and the reaction between NO 2 – and NH 4 + to produce N 2 coexist, but this latter one becomes more predominant when pH decreases …”

“…In a last example, theoretical calculations based on the frontier molecular orbital theory clarified the controversies arising in the steps involved in the production of nitrogen in the catalytic wet oxidation of ammonia showing that the symmetry of the HOMO for NH 4 + matches with the LUMO of NO 2 – leading to the production of nitrogen …”

Fabrication of Efficient Nano-MnOx/ACF Particle Electrodes and their Application in the Electrooxidation of m-Cresol in the 3-D Electrode System

“…m -Cresol is an important chemical raw material that is mainly used as a pesticide intermediate, such as insecticides fenitrothion, thiophosphate, tsumacide, and so forth. , However, little attention has been paid to the application of 3-D electrode technology to the degradation of pesticides. Moreover, m -Cresol is frequently found in industrial wastewater because of its extensive application, and therefore, it is considered as one of the primary pollutants in coal-chemical engineering wastewater …”
