Abstract

Изобретение относится к способу получения электрокатализатора, содержащего пористый углеродный материал-подложку, каталитический материал в форме металла по меньшей мере одного типа и макроциклические соединения, химически связанные с углеродной подложкой и способные образовывать комплексы с одиночными ионами указанного металла или металлов, причем указанный способ включает стадии: i) обеспечения матрицы, способной действовать в качестве агента, образующего пористую структуру при образовании высокопористой электропроводящей матричной углеродной подложки, ii) смешивания матрицы с одним или несколькими веществами-предшественниками каталитического материала, макроциклическими соединениями и углеродом, iii) подвергания смеси матрицы и веществ-предшественников процессу карбонизации, при котором предшественники взаимодействуют и превращают смесь в карбонизированный матричный композит, в котором углеродная часть композита химически связана с макроциклическими соединениями, присутствующими в комплексах с металлом или металлами. Изобретение также относится к электрокатализатору для электрохимических реакций, способу получения мембраноэлектродной сборки с использованием такого электрокатализатора и к топливному элементу, использующему такой электрокатализатор.
