Single-walled carbon nanotubes (SWNTs) with high yield and quality were synthesized using chemical vapor deposition (CVD) over Co-Mo/ MgO nanocatalyst in a fluidized bed reactor. Different parameters such as temperature, the ratio of hydrocarbon source to hydrogen, the flow rate of gas, growth time, the size of catalyst particles, heating rate, and the kind of hydrocarbon source were examined t...
In this scientific research ZnS nanoparticle was synthesized via precipitation method. Two samples were synthesized by this method. The nanoparticle was characterized by XRD techniques, and the size and kind of crystallinity were identified by X-ray diffraction pattern as well. The size measurement has been done by using scherrer's equation. The average sizes of nanoparticles in two sa...
