Abstract
A preparation method of hollow mesoporous carbon nanosphere composite material loaded with gold nanoparticles includes the following steps: (1) in the presence of an initiator, aniline and pyrrole are polymerized in deionized water containing a surfactant to form hollow carbon precursors, and then calcined to obtain hollow mesoporous carbon nanospheres, (2) said hollow mesoporous carbon nanospheres are immersed in a chloroauric acid solution, stirred and then centrifuged to remove the liquid, finally, hollow mesoporous carbon nanosphere composite material loaded with gold nanoparticles are obtained by reduction treatment.
