[中文文摘]将正丁烯在不含金属微粒的催化剂上热解产生了碳纳米管．所用的催化剂是固体酸的氟促进的γ－Ａｌ２Ｏ３和分子筛型的ＨＺＳＭ－５．实验发现，这些固体酸催化剂热解产生碳纳米管所需的温度较低，碳纳米管的产生与催化剂的酸度和酸性位有一定的关联，而且所产生的碳纳米管的结构形态也比较独特．[英文文摘]Carbon nanotubes have been produced by catalytic pyrolysis of n butene on solid acid catalyst at first time. The solid acid catalysts were fluorinated γ Al 2O 3 and HZSM 5 zeolites which did not contain metal particles, as ordinary used in the production of carbon nanotubes . In comparison with the metal particle catalysts, the carbon nanotubes produced in this condition require much lower pyrolysis temperature. The production was found to correlate with acid strength and acid sites of the solid acid catalysts. Some carbon nanotubes with special structures have been distinguished.
