| 英文摘要 | Mesoporous carbon materials with a range of pore sizes were synthesized by a delicately controlled procedure using disordered gamma-alumina as template and sucrose as carbon source. Under optimized conditions, the carbon materials had narrow pore size distribution, large surface area (> 1000 m(2).g(-1)), large pore volume (up to 3.82 cm(3).g(-1)), high mesopore ratio (> 99%), and thin pore walls with thickness of 1-2 graphene layers. In the present work, we employed three types of alumina, and investigated the correlation of their texture with that of the resultant carbon materials. A mechanism for the formation of the carbon materials was proposed and tested against experimental data. A carbon sample prepared by this method can approximately duplicate the pore structure of the template, if the carbon layer in the precursor carbon-covered alumina is complete and sufficiently robust. The mesopores of the carbons had two sources, one from the removal of the template particles and the other from the original pores of the template. Calculated pore volumes strongly support the proposed mechanism. |
