以氯化钴(CoCl2·6H2O)和黄磷为原料，以无水乙醇的水溶液为溶剂，采用溶剂热法制备星形磷化钴(Co2P)微晶，利用X射线衍射、扫描电镜等对产物的物相和形貌进行表征，并分析Co2P的生长机理和形貌演变过程。结果表明，所得产物为纯六方相的Co2P，其形貌为由4～5个花瓣组成的星形结构。星形结构尺寸约4μm，花瓣呈锥形，平均直径约700 nm。反应温度、溶剂中无水乙醇与水的体积比、反应时间等对星形Co2P微晶的形成都具有一定的影响。制备星形Co2P微晶的最佳实验条件为：反应温度180℃，混合溶剂中V(Ethanol)：V(H2O)=1：3，反应时间24 h。

Uniform star-like Co2P microcrystalline was synthesized successfully via a facile solvothermal method, using cobalt chloride (CoCl2·6H2O) as Co-source, anhydrous ethanol and water as solvent. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the products are pure Co2P with a hexagonal phase and have the star-like structure, which consists of four or five petals and each petal shows long-conical shape with the average diameter of 700 nm. Based on this, the effect of solvent ratio for anhydrous ethanol and water, the reaction temperature and reaction time on the formation of star-like Co2P are investigated and then the possible formation mechanism of the star-like Co2P microcrystalline is discussed.
