Metal/porous carbon composite material and preparation method and application thereof

The invention provides a metal/porous carbon composite material and a preparation method and application thereof.The preparation method of the metal/porous carbon composite material comprises the steps that hydroxypropyl methyl cellulose is added into a metal salt solution to be mixed and react, and a gel precursor is obtained; and drying the gel precursor, and calcining at high temperature to obtain the metal/porous carbon composite material. According to the metal/porous carbon composite material as well as the preparation method and the application thereof, the metal/porous carbon composite material is prepared by adopting cheap and easily available raw materials and a pyrolysis synthesis process route which is simple and convenient to operate and relatively low in cost, and the metal/porous carbon composite material has excellent physical and chemical properties; the method can be effectively used in the field of industrial wastewater purification treatment. 本发明提供了一种金属/多孔碳复合材料及其制备方法和应用，所述金属/多孔碳复合材料的制备方法包括
