Catalytic performances of fluorine-doped graphene/Pb composite for thermal decomposition of ammonium perchlorate: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


Summary

Fluorine-doped graphene supported PbO (F-rGO/PbO) composite was ready by a facile water tub technique to review an enchancment technique for its catalytic efficiency in thermal decomposition of ammonium perchlorate (AP). The characterization outcomes confirmed that the PbO with the dimensions of 20 ∼ 30 nm are extremely dispersed on the floor of F-doped graphene (F-rGO). In contrast with different samples, the F-rGO/PbO exhibited superior catalytic efficiency, as 3 wt% of catalyst added in AP, the height temperature for HTD lowered by 124°C, and the height temperature for LTD elevated by 8°C. The launched obvious particular warmth of the thermal decomposition of AP catalyzed by F-rGO/PbO (3603.7 J/g) is 5 instances of that of pure AP (603.5 J/g). The doping of F atoms in graphene elevated BET floor areas of the F-rGO provider and enhanced the content material of hydroxyl teams on the floor of graphene, which improved the thermal decomposition charge of AP. Whereas the extremely dispersed PbO NPs additional elevated BET floor areas of F-rGO/PbO to offer extra energetic websites in the course of the thermal decomposition of AP.
