Experimental and Theoretical Investigation of Porous Carbon Nanospheres for Supercapacitor Application

Energy Storage, Journal Year: 2025, Volume and Issue: 7(3)

Published: March 25, 2025

ABSTRACT Activated carbon holds a promising avenue in the context of energy storage because its special attributes like high surface area, large pore volume, and ease preparation. Herein, we synthesized activated from low‐cost candle soot employed it as an electrode for supercapacitor application. Activation resulted specific area 1679 m 2 g −1 The electrochemical properties (ACS) unactivated (CS) are evaluated three‐electrode setup using 1 M H SO 4 electrolyte. ACS CS exhibited capacitance 467 180 F at current density A , respectively. improved performance is attributed to increase upon activation, which acts reservoir accommodate number electrolyte ions. Furthermore, two‐electrode studies symmetric cells revealed extraordinary 397 . system retained 82% 10,000 cycles 10 This 19.8 Wh kg power 574.8 W We performed functional theory (DFT) simulations validate experimental observations found that quantum greater than CS. barrier ionic diffusion across lower CS, indicating mobility activation.

Photoelectrocatalytic hydrogen production: Hydrogen production principle, performance optimization strategy, application and prospect

Deleted Journal, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 5, 2024

Photoelectrocatalytic hydrogen production is a sustainable energy technology that utilizes solar to decompose water into and oxygen. It offers the advantages of environmental protection sustainability. However, its low efficiency in photoelectric splitting results relatively small production, which severely limits popularization practical applications. This paper reviewed catalytic including principle catalysis, catalyst materials, reaction mechanism kinetics, conditions optimization, as well challenges prospects. The catalysts for efficient strategies improving rate were discussed detail, use catalysts, co-catalysts, integrated optimization photoelectrodes. also covered research on multi-physical field simulation optimization. provided comprehensive theoretical basis guidance related fields.
