A simple and efficient approach for coating multiwalled carbon nanotubes (MWCNTs) with size-controllable SnO 2 nanoparticles by chemical vapor deposition has been developed using tin hydride (SnH 4 ) gas as the source of SnO 2 at 550°C. The size and coverage of SnO 2 nanoparticles can be adjusted by simply controlling the deposition time and the flow rate of the SnH...
Crumpled carbon nanosheets have been successfully synthesized via a catalyst-free solvothermal route at very low temperatures (60-100 o C), using tetrachloromethane as the carbon source and potassium as the reductant. The X-ray powder diffraction pattern indicates that the products are hexagonal graphite. Transmission and scanning electron microscopy show that the thickness of crumpled carbon...
