Abstract: A method for manufacturing an amorphous multielement metal oxide hydroxide film includes: A liquid mixture is formed by dissolving an oxidizing agent selected from a group consisting of potassium permanganate, potassium chromate, potassium dichromate and potassium ferrate, and a reducing agent in a solvent. The oxidizing agent forms an oxometallate anion having a first metal atom with a first valence number. The reducing agent forms a metal cation having a second metal atom with a third valence number. An amorphous multielement metal oxide hydroxide film is deposited on a substrate by soaking the substrate in the liquid mixture. The amorphous multielement metal oxide hydroxide film includes a multielement metal oxide hydroxide having the first metal atom with a second valence smaller than the first valence number and the second metal atom with a fourth valence number larger than the third valence number.
