Catalysts and methods for the hydration and absorption of carbon dioxide

Abstract

The present disclosure provides catalysts comprising zinc and one or more ligands that improve the hydration of carbon dioxide at a zinc metal center, including but not limited to ethylenediaminetetraacetic acid and its derivatives. In certain embodiments, one or more of the ligands on the zinc is water that is replaced with carbon dioxide. In certain embodiments, the zinc catalyst coordinates an appropriate carbon dioxide adsorption solvent to reduce the activation energy for carbon dioxide hydration. Methods and apparatuses that are designed to efficiently utilize sorbents with improved sorption and desorption characteristics, such as those that include an inorganic catalyst or modified carbonic anhydrase, are also disclosed.
