A one-step method for continuous large-scale synthesis of well-defined hollow titania spheres was established by feeding titanium tetrachloride mixed with ethanol vapor to a facile diffusion flame. A mixture of TiCl 4 and C 2 H 5 OH vapor was transported at 100m/s into a flame reactor and condensed into mesoscale droplets due to Joule–Thomson cooling and the entrainment of...
Carbon nanotubes (CNTs) with ultrafine inner diameters have been synthesized successfully through a simple ethanol flame method. The samples were characterized by means of X-ray diffraction (XRD), transmission electron microscopy, scanning electron microscopy, and Raman spectrum. The inner diameter as well as the crystallinity of the CNTs can be influenced greatly by controlling experimental conditions...
