Abstract

Изобретение относится к электроду для электролитических процессов, в частности к катоду, подходящему для выделения водорода в промышленном электролитическом процессе, содержащему металлическую подложку, покрытую внешним каталитическим слоем, содержащим кристаллический оксид рутения, обладающий высокоупорядоченной структурой рутила с длиной связи Ru Ru и Ru О, характеризующейся коэффициентом Дебая-Валлера ниже критической величины. Каталитический внешний слой может содержать оксиды редкоземельных элементов, таких как празеодим. Электрод также может содержать внутренний тонкий каталитический слой на основе платины, обеспечивающий улучшенную защиту от случайных изменений направления тока.
