Carbon nanofiber (CNF) monoliths with excellent properties were prepared by catalytic chemical vapor deposition, using ethylene (C2H4) and a non-supported Cu–Ni alloy as carbon source and catalyst, respectively. The structure, mechanical properties, and specific surface area of the CNF monoliths were characterized for various preparation conditions. The formation of CNF monoliths mainly depended on...
Mesoporous carbon (MC) prepared using colloidal silica templates was used as a support to synthesize TiO 2 /MC composites using a sol–gel method. The TiO 2 content and the crystalline structure of TiO 2 /MC photocatalysts can be tuned by the precursor composition and calcination temperature, respectively. MC and TiO 2 /MC composites were characterized by nitrogen adsorption,...
Multifunctional carbon foams with mean pore size smaller than 200μm were prepared by supercritical foaming, in which toluene and mesophase pitch were used as the supercritical agent and carbonaceous precursor, respectively. The supercritical foaming behaviors and nucleation mechanisms were analyzed. According to the composition of mesophase pitch and micrographs of resultant carbon foams, the interface...
