Description
(54) ЭЛЕКТЮД ДЛЯ ЭЛЕКТРОХИМИЧЕСКИХ ПЮЦЕССОВ(54) ELECTUDE FOR ELECTROCHEMICAL PUCUS
возрастает химическа и электрохимическа коррозионна стойкость кобапьтата, но уменьшаетс его способность давать структуру перовскита. Поэтому дл получени стойкого покрыти величина х в формуле кобальтата, определ юща содержание более т желого элемента, должна соответствовать своему максимальному дл данного состава редкоземельных элементов значению, при котором кобальтат еще обладает структурой перовскита. the chemical and electrochemical corrosion resistance of kobapistat increases, but its ability to produce perovskite structure decreases. Therefore, to obtain a stable coating, the value of x in the cobalt formula, determining the content of the heavier element, must correspond to its maximum value for a given composition of rare earth elements, in which the cobalt still has a perovskite structure.
Пример. Электрод, состо щий из титановой основы с нанесенным на нее слоем кобальтата 1fdQQ T&QJ 3 получают следующим образом , Example. An electrode consisting of a titanium base coated with a 1fdQQ T & QJ 3 cobalt layer on it is prepared as follows,
Приготавливают ,9 измельчением 16,ЗгЭс120з, 1,87гТЬ,, 8,23г СоаОз, содержащей 71% кобальта. Полученный порощок помещают в тигель из окиси алюмини и подвергают обжигу П1Ш 1200° С в течение 15 ч в присутствии воздуха. Охлаждение провод т вместе с печью. Далее продукт измельчают до частиц размером менее 10 ммк. Полученный таким образом черный порощок имеет рентгенограмму, характерную дл перовскита кобальтатов.Prepare, 9 by grinding 16, ZgEs120z, 1.87 gt ,, 8.23 g of SoAOz, containing 71% of cobalt. The resulting powder is placed in an alumina crucible and subjected to firing P1Sh 1200 ° C for 15 h in the presence of air. The cooling is carried out with the furnace. Next, the product is crushed to a particle size of less than 10 MMK. The black powder obtained in this way has an X-ray diffraction characteristic of perovskite cobaltates.
К 1 г порошка добавл ют 1 г гидратированного нитрата кобальта (6 Н2 О), 1 мл воды и I мл изопропилового спирта. Полученную пасту энергично перемешивают до гомогенной суспензии. Слой суспензии кобальтата нанос т кистью на титановую пластану размерами 10x30x1 мм, предварительно подвергнутую пескоструйной обработке, промывке в дистиллированной воде и сушке. После сушки в сушильном шкафу при 100° С в течение 5 мин электрод выдерживают 10 мин при температуре 400°С с продувкой воздухом. Таким образом нанос т 20 слоев кобальтата так, что количество нанесенного продукта составл ет 40 мг/см. Осадок содержит 80% кобальтата и 20% окиси кобальта. Приготовленный анод испытьшают в электролизере дл получени хлора и едкого натра. Электролиз провод т в растворе ЗООг/л NaCI, рН 4, при 80° С. Анодна плотность тока 25 А/дм и потенциал 1100 MB отн. н.к.з.To 1 g of the powder is added 1 g of hydrated cobalt nitrate (6 H2 O), 1 ml of water and I ml of isopropyl alcohol. The resulting paste is vigorously stirred until a homogeneous suspension. A layer of cobalt suspension is brushed onto a 10x30x1 mm titanium plate, previously sandblasted, rinsed in distilled water and dried. After drying in an oven at 100 ° C for 5 minutes, the electrode is held at 400 ° C for 10 minutes with air blowing. In this way, 20 cobalt layers are applied so that the amount of product applied is 40 mg / cm. The precipitate contains 80% cobalt and 20% cobalt oxide. The prepared anode is tested in an electrolytic cell to obtain chlorine and caustic soda. The electrolysis is carried out in a solution of ZOOg / l NaCI, pH 4, at 80 ° C. The anodic current density is 25 A / dm and the potential is 1100 MB rel. n.k.z.
Электрод проработал в течение 100 ч без изменени потенциала.The electrode worked for 100 hours without changing the potential.
При м е р 2. Элekтpoд из титана с покрытием из кобальтата io,4o,i,, СоОз получают и испытьшают , как в примере 1.Example 2. A titanium coated titanium cobalt io, 4o, i ,, CoOS is prepared and tested as in Example 1.
Электрод проработал 500 ч без изменени потенциала .The electrode worked 500 hours without changing the potential.
П р и м е р 3. Электрод с основой из титана и покрытием из кобальтата 1Кс1рдТ6и,СоОэ, приготовленный и испытанный аналогично двум первым , прорабогал без изменени потенциала в течение 500 ч.EXAMPLE 3. An electrode with a titanium base and a Cobalt 1Ks1rdT6i, CoEe coating, prepared and tested similarly to the first two, worked without a change in potential for 500 hours.
Предлагаемый электрод обладает высокой электрокаталитической активностью и устойчивостью потенциала при длительном использовании в качестве анода в хлорном производстве.The proposed electrode has a high electrocatalytic activity and potential stability with long-term use as an anode in chlorine production.
