The carbon nanocoils with various kinds of conformations were prepared by the catalytic pyrolysis of acetylene using the Ni metal catalyst supported on molecular Sieves which was prepared using Fe-containing kaolin as the raw material. There are four kinds of carbon nanocoils conformations produced by this catalyst. The influences of reaction temperature and gas conditions on the conformations of the nanocoils were investigated and the reasons of forming nano-size coils were discussed by comparison with pure Ni metal catalyst.
以含铁高岭土为原料制备的负载于分子筛上的镍金属催化剂，通过乙炔的催化热解制备了具有各种构象的碳纳米线圈。该催化剂产生了四种碳纳米线圈构象。研究了反应温度和气体条件对纳米线圈构象的影响，并通过与纯镍金属催化剂比较探讨了形成纳米尺寸线圈的原因。
