A novel method of NaHCO3 reduction into formic acid with N2H4·H2O over Ni catalyst

Abstract

A novel Ni-catalysed CO₂ reduction with N₂H₄·H₂O was proposed. A 50% yield of formic acid with 99% selectivity was achieved by using a commercially available Ni powder catalyst. The proposed method is simple and environmentally friendly because it requires neither elaborately prepared catalysts, nor high-purity, high-pressure hydrogen.
