Title:
METHOD FOR PRODUCING CARBON DIOXIDE-DERIVED FORMIC ACID USING DUAL CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/113539
Kind Code:
A1
Abstract:
The present invention pertains to a method for producing carbon dioxide-derived formic acid using a dual catalyst, wherein the yield of formic acid produced through carbon dioxide hydrogenation under base-free conditions is improved by adding a Keplerate-type metal-containing nanocluster or a heterogeneous catalyst thereof as a hydration catalyst to a base-free carbon dioxide hydrogenation reaction using a conventional hydrogenation catalyst, and thereby increasing, by means of the hydration catalyst, the content in the reaction solution of bicarbonate ions reacting with the hydrogenation catalyst through a hydration reaction of carbon dioxide.
