September Chementator Briefs

  CO2-to-syngas . . . Scientists from the University of Illinois at Chicago ( www.uic.edu) have developed a catalytic system — molybdenum disulfide and an ionic liquid — to convert CO2 into synthesis gas, (syngas; a mixture of CO and H2 that is used for making liquid fuels and chemicals, such as methanol). Unlike alternative CO2-reduction processes, which only generate CO, the new catalyst system enables the production of syngas directly. The catalyst is also said to be less expensive than alternative reduction catalysts that are based on gold or silver. The results are described in the July 30 issue of Nature Communications.  . . . and CO2-to-methanol Meanwhile, a new catalytic system that directly converts CO2 into methanol has been developed by scientists at the U.S. Dept. of Energys Brookhaven National Laboratory (Upton, N.Y.; www.bnl.gov), in collaboration with researchers from the University of Seville (Spain; www.us.es) and the Central University of Venezuela (Caracas; www.ucv.ve). The catalyst is composed of copper and cerium oxide (ceria) nanoparticles. The research team found that the interface of the two types of nanoparticles is critical to the reactivity of the catalyst system. Laboratory studies…
