Synthesis, properties, and utilization of carbon quantum dots as photocatalysts on degradation of organic dyes: A mini review

Catalysis Communications, Год журнала: 2024, Номер 187, С. 106914 - 106914

Опубликована: Фев. 1, 2024

This review highlights Carbon Quantum Dots (CQDs) as promising photocatalysts for breaking down organic pollutants, particularly in advancing CQDs-based systems degrading dyes. CQDs, used alone or combined with semiconductors, enhance performance. In scenarios narrow bandgaps, CQDs assist separating charges, whereas wider they enable visible/NIR activity through up-conversion luminescence. When integrated into Z-scheme heterostructures, reduce recombination by facilitating electron transfer. Synthesis methods—both top-down and bottom-up—are explored along crucial physicochemical properties. Furthermore, modifying doping integrating functional groups on their surface adjusts characteristics, more effective CQDs-modified future research.

Carbon materials, such as graphene, carbon nanotubes, and quantum-dot-doped metal oxides, are highly attractive for energy storage environmental applications. This is due to their large surface area efficient optical electrochemical activity. In this particular study, a composite material of cobalt oxide quantum dots (Co3O4–CQD) was prepared using nitrate ascorbic acid (carbon source) through simple one-pot hydrothermal method. The properties the material, including functional groups, composition, area, morphology, were evaluated by various methods ultraviolet, Fourier transform infrared, X-ray diffraction, Raman, photoelectron spectroscopy, Brunauer–Emmett–Teller, scanning electron microscopy, transmission microscopy analysis. performance Co3O4–CQD has been studied three-electrode system. results show that at 1 A g–1, delivers higher capacitance 1209 F g–1. asymmetric supercapacitor (Co3O4–CQD//AC) provided 13.88 W h kg–1 684.65 power density with 96% retention. also demonstrated excellent photocatalytic activity (90% in 60 min) degradation methylene blue dye under UV irradiation, which than pristine Co3O4 CQD. demonstrates promising commercial
