Abstract
Herein, a simple ambient conditioned sunlight promoted photochemical reduction reaction is demonstrated for the of nitrate (NO3–) conversion to ammonia (NH3) with the maximum conversion yield of ∼16 mM using iron filings (f-Fe) in the presence of H2O2. Based on a radical scavenging study of reactive species and the characterization of catalyst f-Fe before and after the reaction, a plausible mechanism has been proposed for the ambient conditioned synthesis of NH3. The results associated with the NH3 synthesis have been verified using the 15N isotopic labeled nitrate (15NO3–), which supports the simpler viability of the reported procedure.
期刊介绍：
The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
