Abstract

We present a facile methodology for ammonia (NH 3 ) synthesis using a multiphase iron nanocatalyst (r-IOD (Fe@Fe 3 O 4 @Fe 2 O 3 )) under ambient conditions. Structural and physicochemical analyses of r-IOD were conducted using pXRD, Mössbauer spectroscopy, HRTEM, and XPS analyses, where r-IOD features a three-phase composite architecture, enabling room-temperature reduction of nitrate (NO 3 – ) to NH 3 . The NH 3 formation was confirmed by 15 N isotope labeling and 1 H NMR analysis and quantified by UV-Vis spectroscopic analysis. Postreaction UV-DRS and XRD of r-IOD were also analyzed, indicating Fe-redox participation in the process of NO 3 – reduction.
