提出了一种碳热合成负载型Fe2P纳米粒子的新方法。与传统的H2程序升温还原（TPR）方法不同，该路线使用碳纳米管（CNT）作为载体和还原剂。此外，以Fe_2O_3和磷酸氢铵为前驱体，采用该方法可以制备出Fe_2P纳米粒子。Fe：P前驱体的比例对磷化铁产物的物相组成有显著影响，当磷含量略高于化学计量比时，可以在碳纳米管上得到接近纯的Fe2P。观察到Fe2P产物具有比从常用的磷酸铁前体获得的产物更小的粒度。结果表明，碳热法制备的Fe2P纳米粒子的粒径大小与前驱体的粒径大小有关，这表明通过系统地调节前驱体的粒径大小，可以在碳纳米管上制备出粒径范围较宽的Fe2P纳米粒子.
A novel carbothermal route for the synthesis of supported Fe2P nanoparticles was developed. In contrast to the conventional H2-temperature-programmed reduction (TPR) method, this route uses carbon nanotubes (CNTs) as support and reducing agent. Additionally, Fe2P nanoparticles can be obtained using Fe2O3and ammonium hydrogen phosphate as precursors by this route. The Fe:P precursor ratio has a significant effect on the phase composition of iron phosphide product, and near pure Fe2P can be obtained on CNTs with a phosphorus content a little beyond the stoichiometric ratio. It was observed that the Fe2P product had a smaller particle size than that obtained from the commonly used iron phosphate precursor. It was found that the size of Fe2P nanoparticles obtained via this carbothermal route appeared to depend on the size of Fe-containing precursor, which indicated that it was possible to synthesize Fe2P nanoparticles with a wide size range by systematically adjusting the particle size of Fe2O3precursor on CNTs.
