Abstract:
The polyporous carbon supported tungsten carbide(polyporous C@WC_(1-x)) composite was prepared using hexagonal silica MCM-41 as the hard template by raw material solution impregnation,mechanical milling and simultaneous reduction and carbonization by temperature programming in mixture gas(CH_4/H_2).The structure and morphology of polyporous C@WC_(1-x) composite were studied via X-ray diffraction,transmission electron microscopy and so on.The electrocatalytic property was tested for the electroreduction of p...
