Next-gen catalyst: Alumina-Pt/Ni sets hydrogenation record

In an ACS Applied Materials & Interfaces paper, researchers report on a Ni foam-supported Pt catalyst with an Al2O3 overcoat applied by atomic layer deposition and applicable to hydrogenation.

Scientific Achievement

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.

Research Details

  • 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.
