A simple light-driven process might open the door to reactions that are not easily mediated by other means, according to chemists at the University of Wisconsin, Madison. By way of example, they show that the strategy could lead to an inexpensive way to convert the greenhouse gas carbon dioxide to commercially valuable products.

The team capitalized on a property of hydrogen-capped diamond, a common form of the material, that causes it to emit electrons when . . .
