This research aims to produce N/S-doped Carbon Electrode derived from paper waste (NSCEp) for Electric Double-Layer Capacitor (EDLC). The holds potential as raw material carbon production because of its high cellulose content, abundance availability, and low price. To enhance the electrical performance carbon, an activation step was conducted, followed by double doping with nitrogen sulfur using thiourea. NSCEp result analysed examine specific diffraction peaks, crystallinity, morphology, elemental contents. powder then mixed dispersant a homogeneous slurry electrode film. EDLC assembled in sandwich-like structure, sodium hydroxide (NaOH) solution impregnated separator between film electrodes. assembly conducted under argon atmosphere CR2032 coin cell. results found that provides conductivity 1.21 x 102 S/cm. prepared achieved capacitance value 39.555 F/g determined cyclic voltammetry (CV) analysis. Furthermore, demonstrates initial charge-discharge capacities 300.56 mAh/g 248.88 mAh/g, respectively, at current 0.015 A/g. capacity remains stable up 300 cycles.

Abstract Supercapacitors (SCs) with outstanding versatility have a lot of potential applications in next‐generation electronics. However, their practical uses are limited by short working window and ultralow‐specific capacity. Herein, the facile one‐step in‐situ hydrothermal synthesis is employed for construction NiMo 3 S 4 /BP (black phosphorous) hybrid 3D hierarchical structure. After optimization, displays high specific capacitance 830 F/g at 1 A/g compared to pristine electrode. The fabricated /BP//NiCo 2 /Ti C Tx asymmetric supercapacitor exhibits better 120 0.5 A/g, which also demonstrates energy density 54 Wh/kg 1148.53 W/kg good cycle stability capacity retention 86% 97% Coulombic efficiency after 6000 cycles. Further from DFT simulations, structure shows higher conductivity quantum capacitance, demonstrate greater charge storage capability, due enhanced electronic states near Fermi level. lower diffusion barrier electrolyte K + ions facilitated improved transfer performance /BP. This work highlights significance nanoarchitectonics compositional tunability as an emerging method improving capabilities active electrodes.

The contamination of natural water bodies with dyes and other refractory compounds is a menacing issue in developing nations. Despite stringent laws, industrial effluent not managed efficiently, as it incurs additional cost. Hence, the present research focuses on sustainable mitigation contaminants using self-driven bioelectro-Fenton (BEF) system. iron-activated charcoal (Gt-Fe/AC) cathode-cum-Fenton catalyst used this investigation was synthesized waste green tea extract biogenic agent. catalyst-driven BEF system (Gt-Fe/AC-MFC) achieved maximum power density 111.7 ± 3.1 mW/m2 operating voltage 108 3 mV, while parallelly degrading 20 mg/L Coomassie Brilliant Blue (CBB) dye almost entirely 300 min at neutral pH.
