Integrated CO₂ Capture and Conversion to Formate with a Molecular Platinum Bis(diphosphine) Electrocatalyst.

ABSTRACT: Carbon dioxide is a potentially valuable feedstock for carbon-based fuels or commodities but is only available in dilute streams. Many studies have focused on either the capture and concentration of CO₂ or the reduction of pure CO₂ streams. The direct reduction of sorbent-captured CO₂ in an integrated process would skip the energy-intensive CO₂ concentration and sorbent regeneration step. Herein, we report the electrocatalytic reduction of 1,3-bis-(2,6-diisopropylphenyl)-imidazolium-2-carboxylate (IPr·CO₂), which forms quantitatively from the reaction of sorbent 1,3-bis-(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr) with 10% and 0.04% CO₂ streams, by catalyst [Pt-(dmpe)₂]-(PF₆)₂ (dmpe = 1,2
