在碳纳米管存在下，通过NH 4 VO 3溶液水解制备了一种钒氧化物-碳纳米管复合材料。碳纳米管诱导一维钒氧化物纳米结构的成核，核生长成长的独立的纳米棒。氧化钒纳米棒的长度可达20 μ m，宽度为5-15 nm，具有有序的晶体结构。催化性能测试表明，在300 ℃下，该复合材料对正丁烷部分氧化制顺酐具有良好的催化活性。(c)2006爱思唯尔有限公司保留所有权利。
A vanadium oxide-carbon nanotube composite was prepared by solution-based hydrolysis of NH(4)VO(3) in the presence of carbon nanotubes. The carbon nanotubes induce the nucleation of the 1D vanadium oxide nanostructures, with the nuclei growing into long freestanding nanorods. The vanadium oxide nanorods with the lengths up to 20 mu m and the widths of 5-15 nm exhibit a well-ordered crystalline structure. Catalytic tests show that the composite with nanostructured vanadium oxide is active for the partial oxidation of n-butane to maleic anhydride at 300 degrees C. (c) 2006 Elsevier Ltd.
