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

Catalysis Communications, Journal Year: 2024, Volume and Issue: 187, P. 106914 - 106914

Published: Feb. 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.

Published: Dec. 10, 2023

The preparation of carbon quantum dots (CQDs) from agricultural waste sources stands out as a significant type biomass-based nanomaterials. This is primarily because their minute size, exceptional water solubility, lack toxicity, and impressive stability. Here, were successfully prepared by one-step hydrothermal method using the Avocado peels only solvent. Physicochemical properties CQDs characterized UV–vis, PL, FTIR, XRD, SEM, TEM, HRTEM. diameter was found to satisfy size effect this also supported reduced graphitization. used for removal methyl orange (MO), common anionic dye, an aqueous solution. effectiveness MO directly related pH amount nanomaterial used. Under optimal experimental conditions, with 7.5 mg catalyst dose, 120-minute reaction time, 10, maximum degradation (78 %) achieved.
