Biodegradable methylcellulose biopolymer-derived activated porous carbon for dual energy application

Abstract Activated porous carbon was synthesized from methylcellulose biopolymer through a two-step mechanism involving H 3 PO 4 as an activating agent and then thermally carbonized in tubular furnace under inert atmosphere at 850 °C. The product next rinsed with strong HCl, neutralized deionized water, dried oven 80 Then, to fully understand the behavior of activated carbon, it characterized using techniques such X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), RAMAN spectroscopy, Brunauer–Emmett–Teller (BET), thermal gravimetric analysis (TGA). Additionally, we have created dye-sensitive solar cells electric double-layer capacitor (EDLC) this produced (DSSC). We used above-mentioned prepared for electrode portion Electric Double-Layer Capacitor fabrication, maximized polymer electrolyte film made methyl cellulose (MC) combined 60 wt.% 1-ethyl-3-methylimidazolium tricyanomethanide ionic liquid (IL), maximum conductivity 1.93 × 10 −2 S/cm, electrolyte. fabricated EDLC device shows specific capacitance 60.8 F/gm 5 mV/s scan rate which confirmed by cyclovoltammetry low-frequency impedance plot CH electrochemical workstation. DSSC same material counter-electrode composition that had been yields efficiency 0.86%. fill factor other parameters were also calculated JV characteristics obtained simulator.
