Comparative study on composition, structure, and adsorption behavior of activated carbons derived from different synthetic waste polymers

► Polymer waste can be converted into activated carbon with high surface area. ► Aromatic polymers are better precursors for activated carbon than aliphatics. ► Heterogeneous composition and ash content of raw polymers suppress the porosity of activated carbon. ► Polymer-based activated carbons exhibit potential for environmental remediation and cleanup.
