Abstract
We report the synthesis of tripodal ligand-based nickel catalysts [Ni(tren)(NO3)2] (1) & [Ni(hmtren)(H2O)](NO3)2 (2) and demonstrate its catalytic hydrogenation of CO2 to formate in a basic medium. 1 exhibited the catalytic activity with a turnover number (TON) of 418 in a triethylamine medium at 120 °C. 2 was synthesized by introducing electron releasing methyl groups in 1, which was found to enhance the production of formate and presented a better TON of 638. The catalytic effects of 1 and 2 in the production of formate with NaHCO3 and KOH bases are discussed, and this study validates the use of a non-precious metal catalyst for CO2 hydrogenation in an aqueous medium.
