溶剂热还原法制备棒状LaNiC_2

Preparation of Rod-Shaped LaNiC_2 by Solvothermal Method

以纳米镧镍氧化物前驱体和甲苯为反应物,氢化钙为还原剂,在不锈钢反应釜中于600℃溶剂热条件下成功地合成了棒状LaNiC2。运用XRD,TEM和SEM等对样品的结构和微观形貌进行了分析,并对样品进行了磁性测试。实验结果表明,此方法合成的LaNiC2材料呈棒状、具有铁磁性,同时该法具有简便易行、反应条件温和以及能耗低等优点。

The rod-shaped LaNiC2 was synthesized by solvothermal route in a stainless autoclave at 600℃. In this process, nanooxide precursor and toluene were used as start materials, and calcium hydride was used as reductant. The morphologies and structure of the as-prepared products were examined with XRD, TEM,SEM and magnetic property measurement. The results show that the synthesized LaNiC2 compound was rod-shaped and magnetic. The method has some advantages, such as simple and facile technique, mild condition and low energy-consumption.
