Niu-Zheng with Photocatalyst (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Berkeley Lab scientists Kaiyang Niu (left) and Haimei Zheng, principal investigator, developed a new photocatalyst of metal organic composites that can effectively convert carbon dioxide into the ingredients for fuel. They made the new material, held by Zheng in a glass vial, by exposing a precursor solution to laser irradiation. Credit Marilyn Chung/Berkeley Lab Usage Restrictions Editorial use only.
