The invention relates to the technical field of surface coatings, in particular to a nickel coating catalyst, a preparation method and application of the nickel coating catalyst. After nickel is loaded in activated carbon, the particle size is controlled within 50 microns; coating nickel on the surface of the powder; depositing the powder on the surface of a nickel net by adopting an atmospheric plasma spraying technology; carrying out heat treatment on the nickel net in an atmospheric environment; and carrying out heat treatment on the nickel net in an H2 atmosphere furnace. The coating catalyst prepared by the method has the advantages of high bonding strength with the nickel net, many catalytic active sites and long service life. 本发明涉及表面涂层技术领域，具体涉及一种镍涂层催化剂、制备方法及其应用，在活性炭中负载镍后，将粒径控制在50μm以内；在上述粉末表面包覆镍；采用大气等离子喷涂技术将上述粉末沉积到镍网表面；将上述镍网在大气环境中进行热处理；在H2气氛炉中对上述镍网进行热处理。采用上述方法制备的涂层催化剂与镍网的结合强度较高，催化活性位点多，使用寿命长。
