Carbonaceous source materials have been employed to prepare activated carbon via the carbonization process and activation technique. During the synthesis of the activated carbon, some activating agents (basic, neutral, and acidic forms) have been used to enlarge the surface area, open the pores, and increase the adsorption power. In this work, the obtained bamboo-based activated carbon showed a large surface area, high porosity structure, and desired surface functionalization. Therefore, it is considered a great adsorbent for air purification and wastewater treatment. Adsorption data were fully supported by the Langmuir model or Freundlich isotherm. Apart from pollutants and heavy metal adsorption, activated carbon has been broadly utilized in the electrochemical industry to fabricate supercapacitor electrodes. Unique properties (porous microstructure and high adsorption capacity make it appropriate for the adsorption and desorption of electrolyte ions in non-Faradaic processes without involving chemical reactions. Experimental results confirmed that the prepared carbons showed high-rate capability, excellent capacitance value and long cycle life. � 2023 Seventh Sense Research Group.
