1. A method for manufacturing of an electrocatalyst comprising a porous carbon support material and a catalytic material of metal complexes of macrocyclic compounds chemically bound to the carbon support, said method comprising the steps of:
i) providing a template capable of acting as pore structure directing agent during formation of a highly porous electrically conducting template carbon substrate;
ii) mixing the template with:
1) one or several precursor substances of the carbon support,
2) one or several precursor substances of the macrocyclic compounds, and
3) one or several metal salts or one or several metal salts in a solvent, to form a mixture,
wherein the precursor substances of the carbon support and the precursor substances of the macrocyclic compounds may be the same or different,
and wherein the precursor substances of the carbon support and the precursor substances of the macrocyclic compounds are capable of forming bonds between carbon and macrocyclic compounds, and between macrocyclic compounds and metal; and
iii) exposing the mixture to a carbonization process during which the precursor substances of the carbon support and the precursor substances of the macrocyclic compounds react and transform the mixture into a carbonized template composite in which a carbon part of the carbonized template composite is chemically bound to the macrocyclic compounds and the macrocyclic compounds form complexes with single metal ions or single metal atoms.
