Aerosol-assisted synthesis of monodisperse single-crystalline α-cristobalite nanospheres.
Monodisperse single-crystalline α-cristobalite nanospheres have been synthesized by hydrocarbon-pyrolysis-induced carbon deposition on amorphous silica aerosol nanoparticles, devitrification of the coated silica at high temperature, and subsequent carbon removal by oxidation. The nanosphere size can be well controlled by tuning the size of the colloidal silica precursor. Uniform, high-purity na...
متن کاملHydrothermal synthesis of monodisperse single-crystalline alpha-quartz nanospheres.
Uniformly-sized, single-crystal alpha-quartz nanospheres have been synthesized at 200 °C and 15 atm under continuous stirring starting from uniform, amorphous Stöber silica colloids and using NaCl and alkali hydroxide as mineralizers. Quartz nanosphere size is controlled by the colloid particle size via direct devitrification. Uniform, high-purity nanocrystalline quartz is important for underst...
متن کاملUltrasonic-assisted synthesis of monodisperse single-crystalline silver nanoplates and gold nanorings.
A simple sonochemical route was developed for the crystal growth of uniform silver nanoplates and ringlike gold nanocrystals in a N,N-dimethylformamide solution. The platelike structures were generated from the selective growth on different crystal planes in the presence of poly(vinylpyrrolidone) and the ultrasonic-assisted Ostwald ripening processes. The silver nanoplates in solution served as...
متن کاملSynthesis, characterization, and magnetic properties of monodisperse CeO2 nanospheres prepared by PVP-assisted hydrothermal method
Ferromagnetism was observed at room temperature in monodisperse CeO2 nanospheres synthesized by hydrothermal treatment of Ce(NO3)3·6H2O using polyvinylpyrrolidone as a surfactant. The structure and morphology of the products were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy, high-resolution transmission electron microscopy, and field-emission sc...
متن کاملPalladium/tin bimetallic single-crystalline hollow nanospheres.
Hollow Pd/Sn bimetallic nanocrystals were fabricated by a fast one-pot strategy in an oleylamine system. This method produced a fine single crystalline bimetallic hollow nanostructure. The process and influencing factors of the reaction are also discussed in this work. Bimetallic nanoparticles possessing special hollow structures with single-crystalline nature are expected to have particular el...
