摘要以乙二胺为溶剂，在80-140°C的温度下，用金属卤化物和黄磷直接反应，通过简单的溶剂热法成功地制备了Co_2P、Ni_2P和Cu_3P纳米晶。利用XRD、XPS和TEM对产物的物相、组成和形貌进行了研究。提出了一种可能的机理，并对影响该过程的因素进行了详细的讨论。
Abstract Nanocrystalline Co2P, Ni2P, and Cu3P were successfully prepared through a simple solvothermal process based on the direct reactions of metal halides with yellow phosphorus at rather mild temperatures (80–140°C) with ethylenediamine used as the solvent. XRD, XPS, and TEM were used to study the phases, compositions, and morphologies of the final products. A possible mechanism is proposed and the influential factors in the process are discussed in detail.
