UPTON, NY Physically confined spaces can make for more efficient chemical reactions, according to recent studies led by scientists from the U.S. Department of Energy s (DOE) Brookhaven National Laboratory. They found that partially covering metal surfaces acting as catalysts, or materials that speed up reactions, with thin films of silica can impact the energies and rates of these reactions. The thin silica forms a two-dimensional (2-D) array of hexagonal-prism-shaped cages containing silicon and oxygen atoms.
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Nanjing Normal University recently reported a strategy for boosting the electrocatalytic performance of palladium (Pd) in ethanol oxidation reaction, thus propelling the development of direct ethanol fuel cells (DEFCs).
Scientists based at the University of Oxford as part of the Faraday Institution CATMAT project researching next-generation cathode materials have made a significant advance in understanding oxygen-redox processes involved in lithium-rich cathode materials. The paper, published in
