pyrolysis at 900 °C showed remarkable performance in the adsorption of dye molecules, irrespective of dye charge, especially in the removal of bulky dye molecules, such as acid red 1 (AR1) and JanusgreenB (JGB). For example, the most competitive PDC material showed a Q0 value (maximum adsorption capacity
) 8.1 times that of commercial, activated carbon for AR1. The remarkable adsorption of AR1 and JGB over KOH-900 could be explained by the combined mechanisms of hydrophobic, π–π, electrostatic and van der Waals interactions.

water contaminated with dyes, such as acid red 1 (AR1), JanusgreenB (JGB), methyl orange (MO) and methylene blue (MB), via adsorption. AR1 is a large anionic dye which is toxic and widely applied in the paper industry [44]. JanusgreenB (JGB) is one of the most typical large cationic dyes that is
