In this paper, the ultrafine tin oxides (SnO2) nanoparticles are fabricated by a facile microwave hydrothermal method with the mean size of only 14nm. Phase compositions and microstructures of the as-prepared nanoparticles have been investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It was found that the ultrafine SnO2 nanoparticles...
Three-dimensional (3D) doughnuts-like copper sulfide (CuS) particles were successfully synthesized by a facile microwave hydrothermal method employing polyvinylpyrrolidone (PVP) as the surfactant. The products were characterized by X-ray diffraction, field-emission scanning electron microscopy and UV–vis diffuse reflectance spectra. Results show that the products are selectively fabricated by varying...
