Abstract
A metal oxide electrode catalyst which includes a metal oxide (Y) obtained by heat treating a metal compound (X) under an oxygen-containing atmosphere. The valence of the metal in the metal compound (X) is smaller than the valence of the metal in the metal oxide (Y). Further, the metal oxide electrocatalyst has an ionization potential in the range of 4.9 to 5.5 eV.
