摘要:
以HCl溶液和H2SO4-HNO3的混合酸溶液作为纯化强酸溶液,采用强酸氧化法纯化碳纳米管(CNTs)。将纯化后的CNTs加入到ZnO-Al2O3(ZAO)前驱体溶液中,通过均匀沉淀法,制得CNTs-ZAO复合粉体。采用差示扫描量热仪(TG-DSC)、傅里叶红外光谱仪(FT-IR)、X线衍射仪(XRD)和扫描电子显微镜(SEM)表征纯化前后CNTs和CNTs-ZAO复合粉体。结果表明:在80 ℃、V(H2SO4):V(HNO3)=1:1的条件下,水浴纯化反应2 h,得到纯化效果较好的CNTs。在n(CNTs):n(ZAO)=4:1、ZAO前驱体反应30 min之前加入纯化CNTs,CNTs的表面负载上一层均匀、致密的纳米ZAO颗粒。
Abstract:
Carbon nanotubes(CNTs)were purified with the method of strong acid oxidation, including HCl, mixed acid solution of H2SO4 and HNO3. Purified CNTs were added to precursor solution of ZnO-Al2O3(ZAO), then CNTs-ZAO composite powders were obtained by homogeneous precipitation method. Purified CNTs and CNTs-ZAO composite powders were characteried by thermogravimetric differential scanning calorimetry(TG-DSC), Fourier transform infrared spectrometer(FT-IR), X-ray diffraction(XRD), and scanning electron microscopy(SEM). Results showed that better-purified CNTs were obtained under the conditions of 80 ℃, V(H2SO4):V(HNO3)=1:1, and purification 2 h. Purified CNTs with n(CNTs):n(ZAO)=4:1 and added ZAO precursor 30 min before reaction, CNTs-ZAO compound powders were acquired with a uniform layer of dense nano ZAO particles adsorption on the surface of CNTs.
