Unexpected CO_2 Splitting Reactions To Form CO with N-Heterocyclic Carbenes as Organocatalysts and Aromatic Aldehydes as Oxygen Acceptors

摘要

Carbon dioxide, as the main cause of global warming, attracts much attention around the world. The anthropogenic source of atmospheric carbon dioxide is mainly from the burning of fossil fuel (>60%). An important pathway to cut global carbon dioxide emission is its reduction to carbon monoxide. Carbon monoxide could easily convert water to hydrogen via the industrial well-established "water gas shift reaction".
