摘要
采用电化学氧化方法一步制备了水溶性石墨烯量子点(GQDs),并用透射电子显微镜(HR-TEM)、红外光谱(FT-IR)、塔菲尔极化曲线(Tafel)和电化学阻抗谱(EIS)进行了表征和测试。结果表明,石墨烯量子点对碳钢在1mol/L盐酸介质中具有良好的缓蚀效果,其作用效果为混合型。
Water-soluble graphene quantum dots（GQDs）were prepared by one-step electro-oxidation.The GQDs were characterized by transmission electron microscopy（TEM）,fourier transform infrared spectroscopy（FT-IR）,polarization curves（Tafel）and electrochemical impedance spectroscopy（EIS）.The results showed that the GQDs exhibited good inhibition effect on carbon steel and acted as mixed-type inhibitors in 1mol/L HCl solution.
