Abstract

In an effort to design concepts for highly active catalysts for the hydrogenation of CO₂ to formate in basic water, we have prepared several catalysts with picolinic acid, picolinamide, and its derivatives, and we investigated their catalytic activity. The CO₂ hydrogenation catalyst having a 4-hydroxy-N-methylpicolina-midate ligand exhibited excellent activity even under ambient conditions (0.1 MPa, 25 °C) in basic water, exhibiting a TON of 14700, a TOF of 167 h^-1, and producing a 0.64 M formate concentration. Its high catalytic activity originates from strong electron donation by the anionic amide moiety in addition to the phenolic O^- functionality.
