A highly efficient and stable Pt catalyst was developed for the thermal hydrogenation of styrene and phenylacetylene derivatives. It consists of a Pt nanostructure grown on Ni foam with an atomic-layer deposited alumina overcoating.
Significance and Impact
The new catalyst is designed to minimize use of expensive Pt and maximize its recovery. The test results indicate promise of broad applications in the petrochemical and fine chemical industries.
- The catalyst has the highest reported time of turnover reported for the widely studied styrene hydrogenation reaction, 9.5 x 106/hour.
- Catalytic activity was retained over 10 standard catalyst recycling trials.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
