摘　　要：利用一种简单的溶剂法合成炭微球。采用无水乙醇作为碳源和溶剂,以无水乙醇还原Ni(Ac)2得到的Ni作为催化剂,最佳反应条件:温度500℃、时间48h。采用X-射线衍射仪(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)以及Raman光谱对样品的成分、晶体结构和形貌进行了分析。结果表明:产品为圆球形和纺锤形两种形貌的炭微球,圆球形炭微球直径为1μm～2μm,纺锤形炭微球直径为1μm～2μm,长度为3μm～6μm。此法简便易行,炭微球的产率高达95%以上,且具有较规则的形貌和窄的尺寸分布。Carbon micro-spheres were prepared by a simple solvothermal route in a stainless steel autoclave. Absolute ethanol was used as carbon source and solvent,and nickel as catalyst,obtained by reducing Ni（Ac）2 in absolute ethanol. Carbon microspheres were obtained at 500 ℃ for 48 h. The samples were characterized by X-ray powder diffractometer,scanning and transmission electron microscopy,and Raman spectroscopy. Results showed that there were acicular and spherical carbon particles in the as-prepared samples. The carbon microspheres had diameters ranging from 1 to 2 μm. and the acicular particles had diameters ranging from 1 to 2 μm and lengths ranging from 3 to 6 μm. The yield of carbon micro-spheres was over 95% with a narrow size distribution and perfect shape.
