Abstract

Selective chemical reduction of carbon dioxide to formate anion under microwave irradiation is reported. No formaldehyde or methanol was generated as by products of the CO₂ reduction making the process highly selective. (NH₄)₂CO₃ or dry ice was employed as CO ₂ source. NaBH₄ is used as reducing agent. Aqueous solutions of (NH₄)₂CO₃ or dry ice and NaBH ₄ were subjected to microwave irradiation for a short duration of 5 min. The formation of formate is unequivocally established from the ¹H, ¹³C and DEPT-135 NMR spectroscopic studies. FT-IR and UV-vis have been employed as auxiliary tools to observe the presence of formate ions. The obtained formate has the potential to be used as fuel in fuel cells or in turn can be converted to alkanes or can be used as a precursor for the production of hydrogen. Thus the current process is highly significant for the energy sector and to the chemical industry as well.
