Efficient amino-acid-based reactive capture of CO₂ via nickel molecular catalyst.

ABSTRACT: Reactive capture integrates CO₂ capture and electrochemical conversion into CO - a key building block in the synthesis of industrial chemicals and fuels - avoiding costly regeneration steps and improving efficiency. Amino acid salt solutions, which offer rapid CO₂ capture, facile CO₂ release, O₂ tolerance, and low toxicity, are promising sorbents for reactive capture. However, we find that amino acids can adsorb to common CO-producing catalysts, covering the active sites and deactivating the catalyst, and that they bind less to nickel phthalocyanine (NiPc). Still, when tested for reactive capture systems - where CO₂ supply is inherently limited - NiPc's performance is constrained by its weak CO₂ adsorption and activation. He
