Abstrakt: We propose silver oxide as a cost-effective and sustainable alternative to noble metals for the catalytic reduction of nitroaromatic compounds.  In the present investigation, we have adopted a facile and green synthetic route for the synthesis of silver oxide nanostructures. The prepared nanostructures were found to have crystallized in the cuprite phase and exhibited absorbance over the entire visible range of the electromagnetic spectrum. The catalytic potential of the silver oxide was evaluated by following the kinetics of nitrophenol reduction under ambient conditions and is observed to follow pseudo-first order kinetics with the apparent rate constant kapp = 4.24 x 10-3 s-1 at minimum concentration of the catalyst. We attribute the observed catalytic activity to the freshly generated catalytic surface featuring a partially reduced form of silver oxide. The findings highlight the efficacy of silver oxide in mitigating the environmental pollution originating from the recalcitrant nitroarenes.
