Abstract This work reports the synthesis and testing of doped polyaniline (PANI) Pisum sativum derived activated carbon (PSAC) based composite as efficient electrode material for supercapacitors. The structure, morphology, elemental analysis, surface area materials were studied using x‐ray diffraction Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive x‐rays, Raman Brunauer–Emmett–Teller analysis. electrochemical performance was investigated by deposition it on two different substrates named stainless steel (SS) stainless‐steel mesh (SS mesh). PSAC/PANI exhibited a specific capacitance 446 517 F g −1 SS respectively, at scan rate 5 mV s . showed higher cyclic stability with 91% retention after 10,000 cycles 2 A It delivered 89 101 W h kg power 5000 , respectively.

Poly (3-methylthiophene) (P3MT) was modified by tin disulfide (SnS2) and zirconium (ZrS2) nanoparticles to enhance its electrochemical performance. The surface influence, crystalline structure, performance of the P3MT/SnS2/ZrS2 material were characterized compared with that pristine P3MT. It is found modification can improve structural stability P3MT without decreasing available specific capacitance. properties synthesized electrode evaluated using cyclic voltammetry (CV) AC impedance techniques in 6 M KOH electrolyte.

Abstract In this work, monolithic graphene oxide aerogel (GOA) with a volume of about 4 cm 3 was obtained. order to modify its properties, the GOA samples were irradiated 60 Co gamma rays doses from 10 220 kGy. By using XPS it found that oxygen/carbon ratio in studied decreases as result irradiation. A blue shift G peak is observed Raman spectra which indicates an increase proportion sp bonds during It shown for first time detachment surface layer monolith begins at dose 40 turned out pore sizes on outer side exfoliated are smaller than those inner layers. The removal improves sorption properties towards n‐hexane.
