activated carbons surface [14,15]. From Figure 2, it also reveals
that there were graphite crystal diffraction peaks existing
in W-AC and K-AC, indicating that a fraction of carbon
atoms have aggregated and some micropores have collapsed
in W-AC and K-AC. By careful analysis of XRD patterns, it
can be found that the main peaks’ positions of all samples
were different. This indicated that the activated method can
affect the textural properties of activated carbons and also can
change the carbon atoms arrangement. As a result,W-AC and
K-AC were easy to be transferred from amorphous carbons to
graphite than P-AC.
