Adsorption and electrolytic reduction of molecular oxygen on oxide catalysts. Cathodic reduction of simple and spinel oxides of nickel and cobalt. Zakharkin, G. I.; Tarasevich, M. R.; Khutornoi, A. M.; Makordei, F. V.; Sofronkov, A. N. (Odess. Gos. Univ., Odessa, USSR). Zh. Fiz. Khim., 51(12), 3068-71 (Russian) 1977. CODEN: ZFKHA9. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 67, 66 The cathodic redn. was studied of NiO [1313-99-1] and CoO [1307-96-6], on a rotating ring-disk electrode, as well as oxides of spinel type Co3O4 [1308-06-1] and NiCo2O4 [12017-35-5]. During polarization of the electrode in 1N KOH up to 0 V, breakdown of the oxide phase occurs from formation of the hydroxides Co(OH)2 [21041-93-0] and Ni(OH)2 [12054-48-7]. At f <0.3 V, the hydroxide film is decompd. with the formation in the soln. of Ni2+ and Co2+.

CLASS: ICM: H01M004-62. ICS: H01M004-26; H01M004-32; H01M004-64; H01M010-30. APPLICATION: JP 2001-209128 10 Jul 2001. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) The cathode comprises an active mass mixt. layer held by a conductive metal support; where the layer has a Ni(OH)2 powder based active mass and a binder contg. a copolymer of tetrafluoroethylene and perfluoromethyl vinyl ether. The cathode is manufd. by prepg. a paste of Ni(OH)2 powder, the binder and H2O, forming a sheet by applying the paste on the support, drying and pressing the sheet. .
