Hydrogenation of CO2 to formic acid over a non-precious metal-based polymeric catalyst

Abstract

Catalytic hydrogenation of CO₂ using non-precious metal based heterogeneous catalysts presents a significant challenge and promising opportunity for exploration. We report catalytic hydrogenation of CO₂ using an iron-loaded (<1%) nitrogen rich polymer. This catalyst showed excellent catalytic activity and produced 32.5 mmol of formic acid with a high turnover number of 8419.
