摘要
The immobilization of heterogeneous catalysts on solid support materials is an important task of current catalytic and materials science research. We report here the development of a diamond nanoparticles-based Wilkinson's type catalyst for the reduction of olefins to saturated hydrocarbons. The strategy is based on the formation of rhodium(I)-modified nanodiamonds (NDs-Rh) using a surface-immobilized catechol phosphane ligand, to which rhodium metal centers can be coordinated. The resulting material was characterized by solid-state NMR spectroscopy, X-ray photoelectron spectroscopy, thermogravimetry, and TEM before testing the catalytic efficiency of the catalyst. Excellent hydrogenation efficiency with yields in the range of 85-99% could be obtained with these new NDs-Rh catalysts, which showed in addition good recyclability without loss of activity.
