Chemical vapor deposition (CVD) and normal pulse voltage (NPV) are adopted to construct high-quality graphene-wrapped CuO nanoflowers grown in situ on copper foam (CuO NP@G/CF) as an efficient oxygen evolution reaction (OER) electrocatalyst. The CuO NF@G/CF electrode exhibits a small overpotential of 320 mV to drive a current density of 10 mA cm−2 with a low Tafel slope of 63.1 mV dec−1. This enhancement in OER performance stems from the synergistic effect between highly conductive graphene and hierarchically porous CuO nanoflowers with a number of high-density active sites and open spaces.

正脉冲电压辅助原位制备石墨烯包裹的MOF衍生的CuO纳米花用于水氧化。
采用化学气相沉积法（CVD）和常规脉冲电压法（NPV）构建在泡沫铜（CuO NP @ G / CF）上原位生长的高质量石墨烯包裹的CuO纳米花，作为一种高效的析氧反应（OER）电催化剂。CuO NF @ G / CF电极表现出320 mV的小超电势，以驱动10 mA cm -2的电流密度和63.1 mV dec -1的低Tafel斜率。OER性能的这种增强源于高导电石墨烯与具有许多高密度活性位点和开放空间的分层多孔CuO纳米花之间的协同效应。
