New catalyst upgrades carbon dioxide to fuels found by USTC

Liquid multi-carbon alcohols such as ethanol and n-propanol are desired as renewable transportation fuels. They offer high energy densities, ease of long-range transport, and direct drop-in usage in existing internal combustion engines. Engineering catalysts that favor high-value alcohols is desired. A research team led by professor YU Shuhong from University of Science and Technology of
