dc.description.abstract [EN] Porous few-layer NiFe-layered double hydroxide (PLDH)/graphene oxide (GO) composite electrocatalysts (PLDH/GO) were successfully synthesized through a formamide-assisted coprecipitation method. The ratio of PLDH to GO was optimized, and the structure, morphology and electrochemical properties of samples were systematically investigated. The results show that PLDH with obvious porous and few-layer features uniformly grows on GO, and part of PLDH layer is perpendicular to GO layer and part parallel to GO layer. PLDH/0.1G0 sample exhibits the best oxygen evolution reaction performance with the overpotential of 236 mV at 10 mA cm(-2), and the Tafel slope of 52 mV dec(-1), which is far superior to commercial IrO2 and pure LDH in the same test condition. es_ES
