Abstract This work involved the hydrothermal synthesis of rGO/Co3O4@Ni nanocomposites at low temperatures, followed by annealing 600°C. The microstructural and electrochemical characteristics nanostructured were evaluated in detail. A Co3O4 cubic structure with space group Fd̅3m(227) distinct peaks (220), (311), (222), (400), (422), (511), (440) planes was formed, according to XRD analysis. Raman measurements confirmed presence Co-O bonds provided detailed information on microstructure samples. SEM analysis shape surface architecture demonstrated unique properties porous nanoparticles. existence Co2+ Co3+ ions verified XPS. improved stability a peak capacitance 1056 F/g current density 1 A/g tests carried out an aqueous 1M KOH electrolyte.

In this work, three methods for the synthesis of composites based on poly(ortho-toluidine) (POT) and WS2 are reported: (a) solid-state interaction (SSI) POT with nanoparticles (NPs); (b) in situ chemical polymerization (ICP) ortho-toluidine (OT); (c) electrochemical (ECP) OT. The preparation sheets was performed by ball milling NPs followed ultrasonication solvent N,N’-dimethyl formamide. During POT/WS2 SSI ICP, an additional exfoliation reported. we demonstrated following: ICP method leads to composites, which contain repeating units leucoemeraldine salt (LS) state, while ECP emeraldine (ES) state. Capacitances equal 123.5, 465.76, 751.6 mF cm−2 cases POT-ES/WS2 synthesized SSI, ECP, respectively, were

This study presents the design and development of in situ nitrogen‐doped mesoporous carbon with oxygen‐containing functional groups, which synthesizes from royal poinciana (RP) flowers using a green sustainable approach. The naturally occurring nitrogen biomass serves as heteroatom dopant, imparting redox activity to material. Comprehensive characterization techniques, such X‐ray diffraction, photoelectron spectroscopy, field emission scanning electron microscopy, transmission Raman Fourier transform infrared confirm microstructural chemical features synthesized carbon. Unlike conventional biomass‐derived carbons that primarily exhibit electrical double‐layer capacitance, however, more significantly, RP‐derived demonstrates pseudocapacitive behavior facilitates charge storage through fast reversible Faradaic reactions. A high specific capacitance 834 F g −1 at 1 was achieved, along excellent cycling stability (80% retention after 10 000 cycles). device also exhibited superior rate capability delivered an energy density 18.83 Wh kg power 1000 W , maintaining 90% 5000 cycles 5 . enhanced electrochemical performance is attributed synergistic effects oxygen turbostratic structure, mesoporosity, improve conductivity, ion adsorption, surface
