以碳酸钙(CaCO3)为原料利用溶胶-凝胶法与热分解法合成了CaCO3纳米线,纳米线的制备分为两个步骤,首先利用溶胶-凝胶法合成线状含Ca中间体,这种含Ca中间体是一维线状纳米结构;然后通过含Ca中间体热分解制得CaCO3纳米线,直径为50-80nm,长度达5μm以上,所得CaCO3纳米线为三方晶系,由纳米晶粒组装而成.
CaCO3 nanowires were synthesized from CaCO3 reagent by sol-gel process and thermal decomposition. The preparation of CaCO3 included two steps: In the first step, the wirelike intermediates containing Ca were synthesized by sol-gel process, which are with one dimension wire-like nanostructures; in the second step, the resulting samples were converted into CaCO3 nanowires by thermal decomposition. The diameter and length of the obtained nanowires are 50-80nm and up to 5μm separately. The nanowires are constited of self-assembled nanoparticles and they belong to the trigonal system.
