A decrease in peak broadening compared to f-BP-1300 could indicate the quinone molecules were grafted in more uniform environments within the carbon structure. The amount of anthraquinone loading for f-ABP was calculated from the normalised CV experiments and gave a value of 7.6 ± 0.2 wt.%. This is a large increase from what is seen for f-BP-1300 (5.7 ± 0.2 wt.%) and is comparable to f-CMK-3, suggesting pre-existing functional groups may have caused the low anthraquinone loading in f-BP-1300.
