如图所示，镍纳米球、纳米线和纳米花通过简单的非水溶胶-凝胶路线合成，该路线涉及乙酰丙酮镍与苯甲醇在200摄氏度下在不同磁场的存在下的反应。苯甲醇在该体系中起溶剂和还原剂的作用。与块体镍相比，纳米结构显示出显著的导电性增强。
Nickel nanospheres, nanowires,and nanoflowers are synthesized via a facile non-aqueous sol-gel route involving reaction of nickel acetylacetonate with benzyl alcohol at 200 degrees C in the presence of varying magnetic fields, as illustrated in the figure. Benzyl alcohol acts as the solvent and reductant in this system. The nanostructures show substantial enhancement in coercivity as compared to bulk nickel.
