Recent progress in heterogeneous CO₂ hydrogenation to formic acid towards practical application

초록

Hydrogenation of CO2 to formic acid (FA) has generated widespread interest as a promising solution for H-2 storage as well as eco-benign chemical production. Catalytic CO2 hydrogenation over supported noble metal catalysts shows great promise in the scope of industrial-scale production of FA because of the high-catalytic activity and stability, which stem from the synergistic effect of metal components and various functional catalyst supports. Here, we present a short review of the recent studies in heterogeneous catalytic CO2 hydrogenation to FA, along with technical approaches for the continuous-flow process for the production of FA via CO2 hydrogenation.
