摘要
首先采用一步化学法合成了铁氰化镍纳米微粒,将该产物和热还原石墨烯超声分散后制备出性能稳定的石墨烯-铁氰化镍复合物,利用扫描电镜、透射电镜及傅里叶红外技术对石墨烯和石墨烯-铁氰化镍复合物进行了形貌和结构性能表征。采用电化学技术考察了石墨烯-铁氰化镍复合材料对过氧化氢(H_(2)O_(2))的电催化性能。实验结果表明该电极材料对过氧化氢表现出优异的电催化活性。另外在1×10^(-4)~8×10^(-4)mol·L^(-1)范围内,峰电流与H_(2)O_(2)浓度呈良好的线性关系。该复合电极材料有望用作灵敏检测过氧化氢的传感平台。
Nickel hexacyanoferrate(NiHCF) nanoparticals was synthetized by simple one-step chemistry method. Moreover, graphene-NiHCF composite material was prepared by using ultrasonic dispersion technique. The prepared matreials morphology were characterized using SEM and TEM. Fourier Transform Infrared Spectroscopy(FTIR) indicate graphene-NiHCF was successfully synthetized. Electrochemical experimental results demonstrate that composite material show enhanced electrocatalytic activity towards the reduction of H_(2)O_(2). The reduction peak current of H_(2)O_(2)is linear against the concentrations of H_(2)O_(2)ranging from 1×10^(-4)~8×10^(-4)mol · L^(-1). This graphene-NiHCF composite material is likely to use as a sensitve detection platform for H_(2)O_(2).
