An improved anode for acting as a catalyst for the oxygen evolution reaction in water electrolysis. The anode provides lower overvoltages good kinetics, chemical and mechanical stability low heat of oxygen adsorption and low operating costs. The anode material is formed from a host matrix including at least one transition element preferably Co, Ni or Mn, which is structurally modified by incorporating one or more modifier elements, one of which may also be a transition element, to improve its catalytic properties. Modifier elements including for example Co, Ni, Sr, Li, In K, Sn, C, O, Mn, Ru and Al struc-, turally modify the local chemical environments of the host matrix to provide a …
