Carbon Dioxide (Reduction)
- Brookhaven National Lab. (BNL), Upton, NY (United States). Chemistry Division
The twin problems of global warming, caused by an increase in atmospheric carbon dioxide (CO2) concentrations, and limited fossil fuel resources have stimulated research in the utilization of CO2. These problems would be partially alleviated by the development of artificial photochemical systems that could economically fix CO2 into fuels or useful chemicals. During the past one and a half decades, intensive efforts have been directed toward the photochemical production of carbon monoxide (CO) and formic acid (HCOOH) from CO2. These systems have several common elements: they all contain photosensitizers (such as metalloporphyrins, ruthenium or rhenium complexes with bipyridine), electron mediators or catalysts, and sacrificial electron donors (such as tertiary amines or ascorbic acid). Recent progress along these lines has resulted in advances in our understanding of the interaction of CO2 molecules with metal complexes, and the factors controlling the efficient storage of solar energy in the form of reduced carbon compounds.
