UPTON, NY–The U.S. Department of Energy (DOE) has announced $40M in funding over five years for a new research center aimed at developing hybrid photoelectrodes for converting sunlight into liquid fuels. Chemists from DOE’s Brookhaven National Laboratory will be key partners in this effort, dubbed the Center for Hybrid Approaches in Solar Energy to Liquid Fuels (CHASE), which will be led by the University of North Carolina at Chapel Hill (UNC) and includes additional collaborators at Emory University, North Carolina State University, the University of Pennsylvania, and Yale.

Water is Key in Catalytic Conversion of Methane to Methanol

April 30, 2020 sarah Jonas Catalysis, Chemistry, FUEL

Scientists reveal new details that explain how a highly selective catalyst converts methane, the main component of natural gas, to methanol, an easy-to-transport liquid fuel and feedstock for making plastics, paints, and other commodity products. The findings could aid the design of even more efficient/selective catalysts to make methane conversion an economically viable and environmentally attractive alternative to venting or flaring “waste” gas.
