摘　　要：溶剂热合成是近年来发展迅速的一种制备纳米材料的方法,溶剂是其要素之一.本工作根据文献报道总结了溶剂在合成过程中的作用,并通过对不同条件下合成了纳米硼化镍的实验研究,对结果进行了比较,发现两种方法无论从产物种类还是质量等方面都有很大的差别,并以此为依据对溶剂热反应中溶剂的作用进行了分析.As an important composing element,solvent plays an essential role in the solvo-thermal synthesis.According to the reports on the solvo-thermal process,the functions of the solvent were summarized.In this work,nano-sized nickel borides powders were prepared by both methods of the solvo-thermal synthesis and the chemical reduction reaction for the comparable investigation.By comparing the various as-prepared products,some ideas about the functions of the solvent were confirmed.
