To provide a method for producing nickel oxide which can obtain nickel oxide in which an alkali metal content is ≤100 ppm with respect to a transition metal(s) (including Ni) incorporated therein without producing poisonous gas.
The method for producing nickel oxide includes: a heating stage where a nickel hydroxide-containing precursor in which one or more kinds of first period transition metals other than nickel are comprised, and also, an alkali metal(s) used for neutralizing treatment is left is used as raw material, and the precursor is heat-treated at 300 to 1,000°C, so as to produce nickel oxide in which the average pore size of the grains is ≥25 Å, also the pore volume in the grains is 0.001 to 0.20 cm
