Nanocrystalline WC-Co-Ni catalyst |
| abstract |
The invention discloses a nano-crystalline WC-Co-Ni catalyst, consisting of tungsten carbide, cobalt and nickel. The catalyst is prepared in the following procedures: the tungsten, the cobalt and the nickel soluble salt is mixed according to the mass ratio 100:1 to 20: 1 to 20 and is mixed in distilled water to produce mixed aqueous solution with a concentration of 5 to 30 percent; the mixed aqueous solution is introduced into a spray dryer for spray drying to yield oxide granule precursor; the oxide granule precursor is sintered, reduced and carbonized in the reaction furnace; after that the free carbon is removed in hydrogen atmosphere; and at last the product is cooled to room temperature under the protection of inert gas to yield nano-crystalline WC-Co-Ni catalyst. The process and the devices are simple, the cost is low and the nano-crystalline WC-Co-Ni catalyst yielded has high catalytic performance. Used as electrochemical hydrogen evolution and fuel cell, the electrocatalyst has wide practical prospects. |
