  • Process for preparation of an electrocatalyst
    Patent number: 4871703
    Abstract: 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:(a) dissolving Ru salt(s) and Ni salt(s) in a solvent to form an electrocatalytic salt solution;(b) evaporating the solvent from the electrocatalytic salt solution, leaving a electrocatalytic salt residue;(c) heating the electrocatalytic salt residue in the presence of oxygen to a temperature and for a time sufficient to convert substantially all of the electrocatalytic salt into a electrocatalytic oxide; and(d) bonding the so-formed electrocatalytic oxide to a substrate that would be detrimentally affected if it were to be heated to 480.degree.-500.degree. C.
    Type: Grant
    Filed: December 17, 1987
    Date of Patent: October 3, 1989
    Assignee: The Dow Chemical Company
    Inventors: Richard N. Beaver, Lloyd E. Alexander, Carl E. Byrd
  • Electrochemical cell and process employing a biasing electrode
    Patent number: 4802960
    Abstract: 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.
    Type: Grant
    Filed: February 4, 1986
    Date of Patent: February 7, 1989
    Assignee: The Dow Chemical Company
    Inventors: Glenn A. Eisman, Lloyd E. Alexander
  • Preparation and use of electrodes
    Patent number: 4760041
    Abstract: 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.
