An organic polymer CuPPc-derived copper oxide as a highly efficient electrocatalyst for water oxidation

Herein, we report a novel CuPPc (copper polymeric phthalocyanine)/CF (copper foam) nanoflake material, as precatalyst for the generation of an excellent water oxidation catalyst (WOC). Under optimized conditions, the CuPPc-derived Cu oxide affords a current density of 10 mA cm −2 under an overpotent...

Description
Summary:Herein, we report a novel CuPPc (copper polymeric phthalocyanine)/CF (copper foam) nanoflake material, as precatalyst for the generation of an excellent water oxidation catalyst (WOC). Under optimized conditions, the CuPPc-derived Cu oxide affords a current density of 10 mA cm −2 under an overpotential ( η ) of 287 mV and sustains for at least 50 h in 1.0 M KOH. The strategy presented here is favorable to develop the electrocatalysts for water splitting. A novel CuPPc nanoflake material, derived from organic polymers, was used as an excellent water oxidation electrocatalyst for the first time.
