采用高锰酸钾和硼砂水溶液直接混合的方法，以硼砂作为还原剂和保护剂，制备了稳定性良好的MnO 2纳米粒子。通过透射电子显微镜（TEM）和X射线光电子能谱（XPS）对纳米粒子进行了表征，并通过原位紫外-可见光谱进一步跟踪了其生长动力学。(c)2006 Elsevier B. V.保留所有权利。
Well-stable MnO2 nanoparticles were prepared by directly mixing potassium permanganate and polyelectrolyte aqueous solutions, with the use of polyelectrolyte to serve both as a reducing agent and a protective agent. Such nanoparticles were characterized by transmission electron microscopy (TEM) and X-ray photoelectron spectra (XPS), and their growth kinetics was further traced by in situ UV-vis spectra.
