ABSTRACT:
The present invention provides highly durable electrodes for electrolysis, which are platinum group metal oxide-coated or composite oxide-coated Ti electrodes, comprising a sputtered film of a metal or an alloy consisting of at least one selected from the group of Ti, Zr, Nb and Ta to be transformed the metastable .beta. phase to the .alpha. phase in crystal structure by the heat treatment to prepare the active layer carried on the surface, as an intermediate layer at the interface between Ti substrate and electrocatalytic active layer, and method for preparation thereof. The electrodes allow stable electrolysis at low electrode potentials for long periods of time as highly durable electrodes for electrolysis, especially electrodes for oxygen evolution at high current density.
