摘　　要：提供了一种工艺简单,原料易得,过程消耗低的制备三维网络状SnO2/C纳米链的新方法。首先利用丁烷燃烧得到三维网络状结构的碳纳米材料,然后通过常压化学气相沉积法在碳表面沉积SnO2得到了三维网络状的SnO2/C复合纳米材料。进一步利用扫描电镜(SEM),能谱仪(EDS),傅里叶变换红外光谱仪(FT-IR)以及X射线衍射仪(XRD)对制备的SnO2/C复合纳米材料的形貌、成分及晶体结构进行表征。结果显示,制备的三维网络状SnO2/C复合纳米材料为表面包裹金红石型SnO2纳米颗粒的碳链(SnO2/C纳米链)相互交错而成。与此同时,对三维网络状SnO2/C纳米链可能的生长机理进行了初步的探讨。A new method with simple process,easy availability of reactant and low consumption was proposed for preparing 3-D netlike SnO2/C composite nanomaterials.Firstly,3-D netlike carbon nanomaterials were prepared by butane combustion.And then,an atmospheric pressure chemical vapor deposition(APCVD)method was used to deposit SnO2on the surface of the carbon to form 3-D netlike SnO2/C composite nanomaterials.SEM,EDS,FT-IR and XRD were utilized to characterize the mor phology,constituents and crystalline structure of the prepared 3-D netlike SnO2/C composite nanoma terials.The results revealed that the 3-D netlike SnO2/C composite nanomaterials were composed of criss-cross carbon nanochains wrapping with rutile SnO2 nanoparticles(SnO2/C nanochains).Mean while,the possible growth mechanisms of the 3-D netlike SnO2/C nanochains were discussed.
