Understanding the formation of nitrate from nitrogen at the interface of gas-water microbubbles.

ABSTRACT: Water microbubbles containing Fe²⁺ ions have been found to efficiently transform nitrogen (N₂) to nitrate (NO₃ ^-) by initiating Fenton's reaction at the gas-water interface. Herein, we elucidate the mechanism of the formation of nitrate (NO₃ ^-) from nitrogen (N₂) at the microbubble interface. Several experimental studies were conducted to identify the intermediates formed during the conversion. Our investigation shows the formation of H₂N₂O₂, NO, NO₂, and NO₂ ^- intermediates before yielding NO₃ ^- as the final product. Density functional theory (DFT) calculations provide additional support to our observation by providing insight
