摘　　要：以Na3Rh Cl6为前驱体,TEG(四甘醇)为溶剂,PVP(聚乙烯吡咯烷酮)为稳定剂,AA(抗坏血酸)为还原剂,微波反应120 s,得到了形貌均一,分散均匀粒径大小10 nm的菱形铑纳米颗粒。此外,分别考察了CTAB及油胺两种添加剂对Rh纳米颗粒形貌的影响以及不同形貌Rh纳米颗粒的电催化活性。Uniform and dispersive rhombus Rh nanoparticles with a mean size of 10 nm were synthesized trisodium hexachlororhodate （Na3 RhCI6 ） as a precursor, triethylene glycol （TEG） as a solvent, ascorbic acid （AA） as a reducing agent, and polyvinylpyrrolidone （PVP） as a stabilizer under microwave irradiation for 120 s. In addition, the effects of CTAB and oleylamine on the morphologies of Rh nanoparticles and the catalytic activities of the as- prepared Rh nanoparticles with different morphologies were also investigated.
