Nickel-based alkaline electrolyzed water catalyst as well as preparation method and application thereof

The invention relates to the field of water electrolysis hydrogen production and catalysts, and discloses a nickel-based alkaline water electrolysis catalyst and a preparation method and application thereof. The preparation method comprises the following steps: (1) mixing a mixed solution containing an auxiliary agent and nickel salt with foamed nickel, and then reacting to obtain a Ni/NF catalyst; (2) mixing the Ni/NF catalyst with a cobalt salt solution, and then reacting to obtain a Co-Ni/NF catalyst; and (3) carrying out roasting on the Co-Ni/NF catalyst, NaH2PO2.H2O and C2H5NS in an inert atmosphere. The nickel-based alkaline water electrolysis catalyst prepared by the method is high in activity and low in cost, can be subjected to industrial production, and has a very good application prospect. 本发明涉及电解水制氢和催化剂领域，公开了一种镍基碱性电解水催化剂及其制备方法和应用。其制备方法包括以下步骤：（1）将含有助剂和镍盐的混合溶液与泡沫镍混合，然后进行反应，得到Ni/NF催化剂；（2）将Ni/NF催化剂与钴盐溶液混合，然后进行反应，得Co-Ni/NF催化剂；（3）将Co-Ni/NF催化剂、NaH2PO2·H2O和C2H5NS在惰性气氛中进行焙烧。采用该方法制备的镍基碱性电解水催化剂活性高且成本低廉，同时还可进
