摘要：
Smoked cigarette butts are a non-biodegradable pollutant that has damaged the planet. However, carbon materials derived from cigarette butts have proven to be suitable for various applications. We synthesized cigarette butt-derived carbon via hydrothermal carbonization and chemical activation methods and then converted it to an electrode material for capacitive deionization. The fabricated material, SCC-750, exhibited a relatively high salt adsorption capacity of 10.27 mg g(-1). The excellent CDI (capacitive deionization) performance is due to the high specific surface area of 3,093.10 m(2) g(-1) and a pore volume of 1.754 cm(3) g(-1). This work offers a new method to recycle harmful cigarette butts by converting them into promising electrode materials for capacitive deionization.
