This study reviews the most relevant results on synthesis, characterization, and applications of activated carbons obtained by novel chemical activation with FeCl3. The text includes a description mechanism, which compromises three different stages: (1) intense de-polymerization carbon precursor (up to 300 °C), (2) devolatilization formation inner porosity (between 700 (3) dehydrogenation fixed structure (>700 °C). Among synthesis conditions, temperature, and, lesser extent, impregnation ratio (i.e., mass FeCl3 precursor), are parameters controlling final properties resulting carbons. characteristics in terms porosity, surface chemistry, magnetic analyzed detail. These showed well-developed porous texture mainly micropore size range, an acidic abundance oxygen groups, superparamagnetic character due presence well-distributed iron species. convert these into promising candidates for applications. They widely as adsorbents aqueous phase their acidity, ease separation. stable species carbons’ makes them catalysts Finally, compounds has been shown improve graphitization degree conductivity carbons; consequently being energy storage
