Improving carbon capture from power plant emissions with zinc- and cobalt-based catalysts

Abstract

We report homogeneous catalysts that are soluble and stable in primary amine-based CO₂ capture solvents. The zinc(II) and cobalt(III) complexes, which contain electron-donating multi-dentate anionic ligands, perform catalytic CO₂ hydration at unparalleled observed rates under conditions conducive to industrial post-combustion carbon capture processes.
