Prompt Description

APPROVED. Graphical abstract for the Journal of Inorganic Chemistry. Theme: Ion-doped copper sulfide (CuS) nanomaterials for photocatalysis and energy applications. Central illustration: CuS crystal lattice with uniformly doped ions (Zn²⁺, Fe³⁺, Bi³⁺, Co²⁺, P) substituting Cu sites, depicting atomic-level doping. Left side: Microwave-assisted hydrothermal synthesis process, highlighting rapid heating, short reaction time (minutes), uniform nucleation, and energy-efficient synthesis. Middle section: Mechanism schematic illustrating band gap narrowing, defect states, and sulfur vacancies introduced by ion doping, leading to suppressed electron-hole recombination, enhanced charge separation, and prolonged carrier lifetime under visible-light irradiation. Right side: Application illustrations including photocatalytic degradation of organic pollutants in water, photocatalytic hydrogen evolution (H₂ bubbles), CO₂ reduction, and energy storage devices such as supercapacitors and batteries.
