In this study, we investigated the influence of nitrogen doping on thermal conductivity of carbon nanotubes (CNTs) experimentally and theoretically. The nitrogen-doped CNTs were synthesized by using thermal chemical vapor deposition method and were used to prepare silicone composites. The thermal conductivity of silicone composites with these CNTs improves greatly. A negative influence of nitrogen...
A novel architectures consisting of plum-like Fe3O4 microspheres strung together by nitrogen-doped carbon nanotubes (CNxNTs) was prepared by in situ growth strategy in liquid ethylene glycol (EG). The structure and morphology of the as-prepared samples were characterized by XRD, SEM, and EDS. Results indicated that plum-like Fe3O4 microspheres with the size of about 200–300nm were uniformly self-assembled...
In this paper, two kinds of CNT/TiO2 composites were synthesized by different sol-gel methods. Comparing to the TiO2 /CNTs prepared by method 1 (Tetrabutyl titanate+CNT, H2O), the catalysts synthesized by method 2 (Tetrabutyl titanate, CNT+H2O) showed higher photocatalytic activity and the optimum content of CNT was 1%. Furthermore, diverse reactors were introduced to deal with methyl orange and phenol...
