Autocatalytic Hydrothermal CO2 Reduction with Aluminum to Produce Formic Acid

Utilizing CO₂ as a carbon source for value-added chemicals and fuels could be a promising approach to reducing CO₂ emissions, minimizing global warming. Efficient conversion of CO₂ into formic acid has attracted much attention because of its industrial importance. Water splitting with metal for CO₂ reduction being considered a promising approach, searching for a suitable metal and understanding the possible reaction scheme prove to be meaningful. This chapter focuses on the in situ reduction of CO₂ into formic acid by the hydrogen from the water splitting with Al.
