Fe/MgO催化合成碳纳米管和氮掺杂碳纳米管
Synthesis of N-doped and Undoped Carbon Nanotubes on Fe/MgO Catalysts
摘要
Abstract
N-doped and undoped carbon nanotubes (CN_x and CNTs) were synthesized by the catalytic chemical vapor deposition of ethylenediamine and hexane on Fe/MgO catalysts. The Fe catalysts were obtained by calcination of a Mg/Fe layered double hydroxide (LDH) and a mixture of Mg(NO_3)_2/Fe(NO_3)_3 precursors followed by reduction (Fe-LDH and Fe-Mg(NO_3)_2/Fe(NO_3)_3). The CNTs grown on both catalysts had tubular structures with hollow cores while some of the CN_x grown on Fe-Mg(NO_3)_2/Fe(NO_3)_3 had a different morphology from the conventional bamboo-shape of those grown on Fe-LDH. This special morphology with thick walls had some space between the graphite layers. The molar content of N in the CN_x grown on Fe-LDH was 6.3％, which was a little more than 5.7％ found in the CN_x grown on Fe-Mg(NO_3)_2/Fe(NO_3)_3. However, the latter has more defects and disorders.关键词
