In our study, we proposed a one-pot manner to synthesize MCM-41 samples with different particle size distributions. Polyvinyl alcohol was used as dispersant to synthesize monodisperse MCM-41 nanospheres. Two samples were obtained through two-stage centrifugation. The particle sizes of these two samples were 100–300nm via centrifugation at 12,000rpm and 400–700nm via centrifugation at 4200rpm, respectively...
CuO nanowires have been prepared with high yield at low cost by a facile room temperature solution phase route. The composition, morphology and size of the as-prepared CuO nanowires were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The UV–vis absorption spectra demonstrate that the as-prepared CuO nanowires exhibit...
