1,160,872. Porous catalyst electrodes. VARTA A.G. 7 Oct., 1966 [9 Oct., 1965 (2); 25 March, 1966], No. 45011/66. Heading B1E. [Also in Divisions C7 and H1] A method of making a porous sintered body comprising a catalytic metal which when containing adsorbed hydrogen is both effective as a hydrogen-transfer catalyst at a temperature below 200‹C. and sensitive to air, is characterised in that the catalytic metal in pulverulent form and containing adsorbed hydrogen is treated to remove the adsorbed hydrogen and is thereafter moulded with the application of pressure and heat to form the porous sintered body. Catalytic metal is defined as a metal effective as a hydrogen-transfer catalyst, that is a hydrogenation or dehydrogenation catalyst e.g. Fe, Co or Ni particularly in Raney form. Examples describe the manufacture of electrodes from nickel boride and covered with (1) Cu and or carbonyl nickel and (2) powdered A1. The catalyst may be promoted with Cu, Hg, Ag or Cd. Pore formers may be M.g, Ca, Zn, B, Al or Si. |
