Caption

a) Caffeine adsorption capacity of ICY-AM and ICYAN-PA adsorbents as a function of adsorbent surface charge, illustrating the influence of pH on adsorption performance, and b) optimized geometry of the most stable caffeine–adsorbent complexes for ICY-AM and ICYAN-PA, depicted in two different visualization modes: the left view uses stick representation, while the right view displays the adsorbents in surface representation. The bottom panel features a zoomed-in inset (center) that clearly illustrates the binding mode of caffeine and the primary interactions at the adsorption site. Color code: Hydrogen (white), Nitrogen (blue), Oxygen (red), Carbon in adsorbents (orange), Carbon in caffeine (cyan).
