Researchers from Oregon State University, The Ohio State University, and the Southern University of Science and Technology in Shenzhen, China, have helped characterize a novel electrocatalyst developed by collaborators at Yale University and helped explain its improved efficiency for deriving methanol from carbon dioxide. The researchers’ dual-site catalyst is the result of combining two different catalytic sites at adjacent locations, separated by about 2 nanometers, on carbon nanotubes. The new design increases the methanol production rate, and less of the electricity used to catalyze the reaction is wasted. “The hybrid catalyst was found to exhibit unprecedented high catalytic efficiencies, nearly 1.5 times higher than observed before,” said Zhenxing Feng, one of the scientists involved in this study.
