摘要
Carbon hollow spheres (400-600 nm) and vessels (400 nm x 3000 nm) have been synthesized from sp(3)-CCl4 at 190 and 230 degreesC, respectively. The HRTEM images and Raman spectra reveal the sp(2) nature of the as-obtained products, indicating that the transformation from carbon sp(3) to sp(2) occurs in the reactions. The possible mechanism has also been proposed.
