Energy Technology, Volume 13, Issue 11, November 2025.Functionalizing carbon nanotubes (CNT) with the mesitylcopper (Cu‐mes) complex modifies the surface of CNT, developing Cu‐Pt alloys and Cu‐species. The result is a modified Pt electronic structure that promotes the catalytic activity of the 5 wt% Pt/CNTCu‐mes nanocatalyst for hydrogen and oxygen evolution reactions, and oxygen reduction reaction.
