Abstract
Carbon nanorods (CNRs) were fabricated from natural based nanocrystalline cellulose through a simple thermal treatment at 800, 1000 and 1200°C. The morphology, structure and electrochemical performance of CNRs were characterized by atomic force microscopy, Raman spectroscopy, nitrogen adsorption-desorption, cyclic voltammetry and electrochemical impedance spectroscopy. Their electrosorption performance in NaCl solution was studied. The results show that CNRs treated at 1200°C exhibit the highest specific capacitance of 264.19 F g-1 and electrosorption capacity of 15.12 mg g-1 with the initial NaCl concentration of 500 mg l-1, due to their high specific surface area and low charge transfer resistance.
