1. the preparation method of a loaded transitional metal phosphide catalyst, it is characterized in that:

  • take red phosphorus as phosphorus source, one or more metallic elements of take in group vib and/or VIII family are metal component, take absorbing material as carrier, under microwave heating condition, prepare transition metal phosphide catalyst;

    According to carrying metal active component 1.15 * 10 on every gram of carrier -2-4.6 * 10 -5mol meter, is supported on the soluble-salt of metal active constituent on carrier by infusion process, then with red phosphorus mixed grinding, and P elements and intermetallic mol ratio>

    =1 in red phosphorus;

    Under argon gas or hydrogen atmosphere, utilize heating using microwave 2-30min;

    Under last normal temperature, take mol ratio as 90-99;

    the N of 1-10 2/ O 2atmosphere passivation obtains finished product for 3-5 hour;

    In finished product, the mol ratio of metal and phosphorus is 3;
