No single clean energy technology can rein in carbon dioxide emissions. Researchers at the Berkeley Lab aim to add artificial synthesis to our renewable energy portfolio. The technology uses sunlight to turn CO2 and water into chemical fuels. Over the past decade, research led by Peidong Yang has yielded new classes of semiconductor materials to efficiently capture sunlight for this process, and new types of catalysts to promote the chemical reactions Series: "Cal Future Forum: Our Changing World" [Science] [Show ID: 33080]
