Abstract This work reports the facile preparation of single‐walled carbon nanotubes (SWCNTs) noncovalently functionalized with 3d transition metal (II) phthalocyanines MPcs (M=Mn, Fe, Co and Ni) their electrochemical evaluation towards oxygen evolution reaction (OER) in alkaline media. The modification SWCNTs improved potential required for 0.1 M 1 KOH by lowering approximately 120 mV comparison unmodified SWCNTs, at a current density 10 mA cm −1 . onset hybrids is close to bulk Ni electrode significantly outperforms Ir black electrodes solution. Nickel, cobalt iron showed auto‐activation during extended cyclic voltammetry long‐term chronoamperometric measurements both concentrations. excellent electrocatalytic activity obtained straightforward method synthesis opens possibility exploring proposed materials applications anion exchange membrane water electrolysis (AEMWE).
