摘要: 以埃洛石纳米管(HNTs)为模板和聚乙烯醇(PVA)为碳源,采用水热纳米浇筑法成功制备出碳纳米棒。方法涉及3步,即在HNTs中浇筑PVA,碳化和模板移除。采用一系列表征手段如XRD、FT-IR、SEM、TEM、Raman、XPS、SAED和N2吸附-脱附等表征碳纳米棒的形成和结构。具有一维棒状结构的碳纳米棒具有高的比表面积(408 m2·g-1)和典型的介孔特征。

Abstract: A novel method to prepare carbon nanorods through hydrothermal nanocasting method was presented using halloysite nanotubes (HNTs) as the template and polyvinyl alcohol (PVA) as the carbon source. This method involved in three steps, i.e. nanocasting PVA in HNTs, carbonization and etching removal of template. A series of characterization, such as XRD, FT-IR, SEM, TEM, Raman, XPS, SAED and N2 adsorption-desorption were used to detect the formation and structure of the as-prepared carbon nanorods (CNRs). The CNRs with a 1D rod-like structure were of high specific surface area (408 m2·g-1) and possessed typical mesoporous characterization.
