摘要
以Cu(Ac)2和多壁碳纳米管(MWCNTs)为原料,乙二醇(EG)作溶剂和还原剂制备了Cu2O/MWCNTs纳米复合材料。通过傅里叶红外光谱(FT-IR)、X射线粉末衍射(XRD)和透射电镜(TEM)对材料进行了表征,探讨了Cu2O以纳米粒子负载于MWCNTs表面的形成机理,并测试了复合材料对NOx的气敏性。结果表明Cu2O纳米粒子能够以键合作用负载在MWCNTs表面,Cu2O以纳米粒子形式有效负载是MWCNTs表面的化学吸附中心和Cu2+使用量的综合作用结果;Cu2O的负载有效增强了MWCNTs对NOx的气敏范围和灵敏度。
Nano-composites of multi-walled carbon nanotubes （ MWCNTs ） loaded cuprous oxide （Cu20） was synthesized using Cu （Ac）2 and treated MWCNTs as source precursor. The nano-composites was characterized by X-ray powder diffraction （XRD）, fourier transform infrared spectroscopy （FT-IR）, Transmission electron microscope （TEM）. The results showed that. Cu20 nanoparticles were deposited uniformly onto the surface of MWCNTs. The mechanism of Cu20 loaded on MWCNTs was discussed. There are two factors that determined the Cu20 effective load. The factors are chemical adsorption center of MWCNTs surface and Cu2＋ content. Cu20 load effectively enhance the MWCNTs for NOx gas sensor range and sensitivity.
