Chlorophyll interpolated nafion-membrane for flexible supercapacitor with methanol and ethanol oxidation reaction

This paper delineates the design and fabrication of Nafion and Chlorophyll-Nafion membranes in originating the flexible supercapacitors and direct alcoholic fuel cells. Herein, the procedure for the extraction of Chlorophyll from the plant leaves is demonstrated. An advanced flexible membrane of Nafion-Chlorophyll is synthesized by a facile synthesis procedure. Here, we examine the Nafion-Chlorophyll membrane as a supercapacitor and its performance is enhanced in the absence of light using three-electrode setup. The chlorophyll intercalated membrane electrodes depict a specific capacitance of 0.237 μ F cm^-2 when the light is just on from the dark and decreased to 0.15 μ F cm^-2 after 60 min of light exposure. Moreover, the membrane electrode also exhibits capacitive retention of 89.04 μ A cm^-2 respectively. Thus, the fabricated flexible chlorophyll membrane shows huge proficiency in portable and flexible energy storage platforms.
