1. A preparation method of hollow mesoporous carbon nanosphere composite material loaded with gold nanoparticles, which comprises 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, finally obtaining the hollow mesoporous carbon nanosphere composite material loaded with gold nanoparticles by reduction treatment.
