A team of scientists has discovered a single-site, visible-light-activated catalyst that converts carbon dioxide (CO2) into "building block" molecules that could be used for creating useful chemicals. The discovery opens the possibility of using sunlight to turn a greenhouse gas into hydrocarbon fuels.

The scientists used the National Synchrotron Light Source II, a U.S. Department of Energy (DOE) Office of Science user facility at Brookhaven National Laboratory, to uncover details of the efficient reaction, which used a single ion of cobalt to help lower the energy barrier for breaking down CO2. The team describes this single-site catalyst in a paper just published in the Journal of the American Chemical Society.
