Synergic effects enhance the catalytic properties of alpha-Ni(OH)2-FeOCPc@rGO composite for oxygen evolution reaction

α-NiFeOCPc@rGO composite as durable and high performance OER catalyst able to sustain a stable current of 10 mA cm−2 during 8 h of continuous electrolysis at 1.64 V vs RHE, in 1.0 mol dm−3 KOH solution. The material was prepared stacking rGO sheets sandwiched in between monolayers of crystalline alpha nickel hydroxide nanoparticles covered up with octacarboxyphthalocyaninate iron(II) complex.347
