The invention is a method for preparing electrocatalytic oxides and applying them to substrates that cannot be heated to temperatures sufficiently high to convert electrocatalytic salts into electrocatalytic oxide comprising:

Process for preparation of an electrocatalyst

In an electrolysis cell, a separator having a buried wire screen is disclosed. The screen is connected to a bias voltage source to repel unwanted ionic migration across the screen and hence the separator.

Electrochemical cell and process employing a biasing electrode

A substrate is coated with a solution of metal oxide precursor compounds and an etchant for etching the substrate, the metal oxide precursor compounds are thermally concentrated by removing volatiles therefrom, and the so-concentrated metal oxides precursors are thermally oxidized in-situ on the substrate. The so-formed compositions are useful, e.g., as electrode material in electrochemical apparatuses and processes.
