Energy storage and supercapacitors: Activated carbon can be used as an electrode material in supercapacitors and energy storage devices. Its high surface area and porosity allow for efficient charge storage, making it valuable in energy storage applications. Adsorption: Activated carbon has exceptional adsorption capabilities, meaning it can attract and retain a wide range of chemicals, gases, and impurities onto its surface. This makes it effective in purifying air and water by removing pollutants, toxins, odors, and volatile organic compounds (VOCs).
