Porous catalysts that capture carbon dioxide and convert it into a useful fuel, analogous to the ability of plants to convert carbon dioxide into biomass. Computer modeling shows how the functional groups inside a porous solid substrate can be tuned to obtain accelerated reactions to split carbon dioxide and produce useful products (Design: Jingyun Ye).
