High-activity nano-porous electrolyzed water catalyst as well as preparation method and application thereof

The invention discloses a high-activity nano-porous electrolyzed water catalyst, a preparation method thereof and application of the high-activity nano-porous electrolyzed water catalyst in electrolyzed water. The chemical composition of the main active component of the catalyst is FeaCobNicZrdPte, a, b, c, d and e all represent atomic ratios, a is more than or equal to 25 and less than or equal to 35, b is more than or equal to 3 and less than or equal to 9, c is more than or equal to 4 and less than or equal to 10, d is more than or equal to 2 and less than or equal to 7, e is more than or equal to 48 and less than or equal to 60, and a + b + c + d + e = 100; the main active component has a nano-porous structure and contains face-centered cubic phase nanocrystals. The preparation method comprises the following steps: preparing materials according to the chemical formula of a precursor, and uniformly smelting to prepare master alloy; a ', b', c ', d' and e 'represent atomic ratios, 60 < = a' < = 70, 8 < = b
