Manganese dioxide (MnO2) nanoparticles have been prepared through the redox reaction between KMnO4 and the nonionic surfactant Triton X-100 with the aid of rod-like micelles, hexagonal liquid crystals and reverse micelle templates, in which Triton X-100 acts both as template and reductant. MnO2 nanorods (20 50 nm in diameter) can be obtained in rod-like micelles and hexagonal liquid crystals, whereas MnO2 nanospheres (about 85 nm in diameter) are formed in reverse micelles. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are used to characterize the products. Modification of MnO2 nanoparticles by rutin has been discussed using fluorescence spectra and UV vis spectra, and the free radical eliminating investigations of surface-modified MnO2 nanoparticles with rutin show that MnO2 nanoparticles can improve the free-radical-scavenging activity of rutin.
