    • 专利摘要:
    This invention relates to a method of producing metal electrodes by treating a metal electrode substrate so as to coat the substrate surface with a homogeneous solution of the compounds of (i) at least one metal selected from a first group of iron, cobalt, nickel and manganese (ii) at least one other metal selected from a second group of molybdenum, tungsten and vanadium, each of which compound is capable of thermal decomposition to the corresponding metal oxide. The coated substrate is then thermally decomposed and the oxide-coated substrate is cured in a reducing atmosphere at elevated temperature. Substrates coated with Ni-Mo oxides are preferred. The electrodes thus produced exhibit very low overvoltage, are of high stability with respect to their activity and can be used as cathodes for the electrolysis of water or brine.

    The invention relates to the electrochemical production of electrodes used in electrochemical processes, and can be used in the processes of electrolysis of water, the production of chlorine and alkali.
    The aim of the invention is to reduce power consumption when using an electrode.
    Example 1, Ni and Mo alloy.
    Solutions containing required. The atomic ratios of nickel and molybdenum were obtained by mixing the measured 3.4 molar volumes of the nickel nitrate nickel nitrate iodine seventh molar part of ammonium paramolybdate. The solutions obtained were stabilized by adding concentrated ammonia to form a clear dark blue solution.
    The coating was prepared by spraying a coating solution containing 60 at,% nickel and 40 at,% molybdenum onto a nickel network. Then, the coated mesh was heated in an open flame to red hot to decompose salts and metals to oxides. The operation was repeated until a satisfactory coating was obtained. The resulting oxidized grid was heat treated for 1 hour at 500 ° C. By means of x-rays, powder diffraction, the main phase was identified as a face-centered cubic structure with an elemental cell parameter of 3.585 A, (cf. nickel 3.524 A), which confirmed the presence of a nickel-molybdenum alloy with a molybdenum concentration of 13.5 at.%. The average crystalline size, determined from the peak width at half the peak height of the diffraction peak 311, was equal to 43 A. The face-centered cubic symmetry of the structure is confirmed by indication of 111, 200, 220, 311 and 222 reflections.
    The potential of the coated electrode): after correction by 1 was equal to 60 mV compared to a reversible hydrogen electrode (R HE) at a current density of 0.5 A / cm-2 at 30 wt.% Per volume KOH at 1Q ° C when used as hydrogen cathode in a standard cell of three compartments.
    Example 2. The coating was obtained by dipping the nickel mesh into the coating solution j contents

    storing 80 at.% nickel and 20 at.% molybdenum. First of all, as in example 15, the coating material was converted to metal oxides and reduced to 5 at 500 ° C for 1 h. Most of this composition was identified as a face-centered cubic structure with elementary cell parameter q 3,567 A (cf. nickel 10 3,524 A), confirming the presence of a nickel-molybdenum alloy with a molybdenum concentration of 9.7 at.%. The average crystalline size (see example 1) was 54 A.
    J5 The potential of the coated electrode is 90 mV in comparison with a reversible hydrogen electrode at a current density of 1 A / cm at 30 wt.% Per volume of KOH at 70 ° C and in the same use, 20 as in Example 1.
    Example 3. NiW alloy. 5 ml of a solution containing 1.29 g of anhydrous nickel chloride were dissolved in 20 ml of anhydrous methanol and. 25 was mixed with 5 ml of a solution containing 1.453 tungsten hexachloride dissolved in 20 ml of anhydrous methanol. The resulting homogeneous solution contains nickel and tungsten in an atomic 2Q ratio of 73/27.
    The coating was obtained by means of dipping the agglomerated nickel flag into the coating solution. Then the nickel flag covered with metal salts was treated as in Example 1 to convert the salts to metal oxides and then recover at 500 ° C for 2.5 hours.
    The main phase in this composition was identified as a face-centered cubic structure with a parameter: an elementary cell of 3.564 A (cf., with nickel of 3.524 A), confirmed, and the presence of a nickel-tungsten alloy with a tungsten concentration of 8.4 at.%.
    The electrode potential of the coated electrode at a current density of 1 A / cm at 70 C is equal to 134 mV in comparison with the reversible hydrogen electrode and the usage that is used in Example 1.
    Example 4. The subsequent results of the electrochemical activity of electrocatalytic coatings, 55 obtained from homogeneous solutions containing varying concentrations of molybdenum, show that with a decrease in the content of molybdenum in solution 35

    the same 9 at.% marked drop in activity. Measurements were carried out using 30% aqueous KOH as electrolyte, and measuring the potential of the cathode in comparison with a reversible hydrogen electrode was carried out with the passage of a current of 1 A / cm
