Porous nano-carbon materials have been widely utilized as fascinating absorbents, catalyst supports, and energy storage materials. Carbon nanotubes (CNTs) have attracted great attention as electrode materials for electrochemical energy storage due to their unique electrical and mechanical properties. Gelatin is a mixture of peptides and proteins by partial hydrolysis of collagen extracted from various animal by-products. It can be an efficient precursor for producing the high performance carbon electrodes owing to its low-cost and high nitrogen/carbon contents. In this work, nitrogen containing highly porous carbon nanotube aerogels were achieved by the 2-step process consisted of the hydrothermal treatment and high-temperature pyrolysis on the self-assembled gelatin-CNT hydrogels. The structure and chemical composition of the gelatin-derived carbon coated CNT aerogels were characterized, and their electrochemical properties were investigated for the supercapacitor electrodes. |
