▎ 摘  要

Fluorine-doped graphene supported PbO (F-rGO/PbO) composite was prepared through a facile water bath method to study an improvement strategy for its catalytic performance in thermal decomposition of ammonium perchlorate (AP). The characterization results showed that the PbO with the size of 20 similar to 30 nm are highly dispersed on the surface of F-doped graphene (F-rGO). Compared with other samples, the F-rGO/PbO exhibited superior catalytic performance, as 3 wt% of catalyst added in AP, the peak temperature for HTD reduced by 124 degrees C, and the peak temperature for LTD increased by 8 degrees C. The released apparent specific heat of the thermal decomposition of AP catalyzed by F-rGO/PbO (3603.7 J/g) is five times of that of pure AP (603.5 J/g). The doping of F atoms in graphene increased BET surface areas of the F-rGO carrier and enhanced the content of hydroxyl groups on the surface of graphene, which improved the thermal decomposition rate of AP. While the highly dispersed PbO NPs further increased BET surface areas of F-rGO/PbO to provide more active sites during the thermal decomposition of AP.
