    摘要： This invention provides a platinum/carbon nanotube catalyst applicable to heterogeneous asymmetric hydrogenation, which is fabricated by supporting platinum on carbon nanotube carriers. The catalyst is prepared by the steps of: heating purified carbon nanotubes in nitric acid, filtering and washing the same with water until pH value of the filtrate becomes neutral, drying the carbon nanotubes; immersing the carbon nanotube carriers obtained in an aqueous chloroplatinic acid solution and carrying out ultrasonic treatment at room temperature; immersing the mixture of the carbon nanotubes and the aqueous chloroplatinic acid solution under stirring; drying the material by heating to 110° C. from room temperature and maintaining this temperature; grinding the product to fine powders, reducing the fine powders with an aqueous sodium formate solution under a heating condition, filtering and washing the product with deionized water, and drying the product. The invention further provides a process for preparing a platinum/carbon nanotube catalyst and a use thereof in heterogeneous asymmetric hydrogenation.

    摘要： The invention relates to a process for hydrogen transfer to chemical compounds, wherein hydrogen transfer is carried out in a supercritical or subcritical phase using stabilized and dispersed metal particles. The invention further provides for the use of metal colloids stabilized by organic compounds or embedded in organic compounds as catalysts in a process for hydrogen transfer to chemical compounds in a supercritical or subcritical phase so as to avoid the formation of free-radical intermediates during hydrogen transfer.
