Abstract

The porphyrin-based catalysts for water splitting are composites of porphyrin or metalloporphyrin active ingredients, conductive carbon (e.g., graphene sheets, vapor grown carbon fiber, carbon black, etc.), and a polymer or binder that may be coated on a glassy carbon electrode. The polymer or binder may be Nafion oil or polyvinylidine difluoride. The porphyrin may be a porphyrin having a transition metal or hydrogen at its center, and may be halogenated and/or have a thiophene substituent.
