Carbon Dioxide as a Raw Material: The Synthesis of Formic Acid and Its Derivatives from CO₂

TLDR

Carbon dioxide is increasingly used as an ecologically and economically valuable raw material, and its catalytic reduction to formic acid and derivatives has been intensively studied. The study seeks efficient reaction conditions and activation mechanisms to convert the stable CO₂ molecule into desired products. Recent advances in CO₂‑to‑formic‑acid synthesis, driven by mechanistic insights and new catalysts, suggest that industrial‑scale production is becoming feasible.

Abstract

Abstract The use of carbon dioxide as a raw material for chemical syntheses is an ecologically and economically valuable extension to the carbon sources used at the present time. In order to convert the thermodynamically stable and comparatively unreactive CO 2 molecule into the desired product in an efficient manner, suitable reaction conditions and activation mechanisms must be found. The catalytic reduction of CO 2 to formic acid and its derivatives has been intensively studied in recent years. A number of new approaches to the synthesis of formic acid from CO 2 have reached such a state of knowledge that continuing development may well lead to industrial‐scale operation in the near future. This can to a large extent be attributed to the fruitful interaction between investigative work into reaction mechanisms and the development of new catalytic systems.
