“…The interaction of MK and CQDs could be seen from the C1s high-resolution spectra in Figure 7d, where the composites exhibited C-O/C-N, C=O, and a carboxyl group (COOH) Nugraha et al, 2021;Ratlam et al, 2020). Additionally, the N element was also shown through the N1s highresolution spectra in Figure 7e.…”

“…Additionally, the N element was also shown through the N1s highresolution spectra in Figure 7e. The MK/CQD composites showed the binding energies of pyridic NH2 and C-N Nugraha et al, 2021;Ratlam et al, 2020). The adsorption test was performed on MK samples to identify the optimum amount of adsorbent required to reach maximum adsorption.…”

The modification of kaolin with nano-size fillers has exhibited excellent performance in the adsorption process. Carbon quantum dots (CQDs) are the new generation of nanoparticles that have attracted interest for their utilization as modifiers. In this study, a composite of metakaolin(MK)/CQDs was synthesized and tested for methylene blue (MB) removal. The heating and acid-alkali treatment of kaolin transformed it into MK. The interaction between MK and CQDs was analyzed using XPS to detect the binding of pyridic NH2 and C-N. By loading CQDs into the kaolin matrix, the surface area was improved and the removal of MB increased. For a lower MB concentration at 5 ppm, the removal efficiency could reach 96%. The composite exhibited good regeneration through the recyclability test.

“…CQDs are one of the materials that can be produced by using a whole world of materials, as long as they can act as a carbon precursor. Some of these materials are low cost such as citric acid, proteins, and carbohydrates; but can also be produced from waste materials such as bagasse of Sugar cane, Sugar cane juice, , peels of fruits and vegetables, nuts, − other organic and plastic waste, , juices of fruits and vegetables . It can even be produced from ashes .…”

Across the globe, the task of providing clean and safe drinking water is getting harder. Organic contaminants, including dyes and pharmaceutical medications, are a significant environmental threat, especially in aquatic bodies due to their uncontrolled emission. Therefore, a method for their degradation in water bodies that is both environmentally friendly and commercially feasible must be developed. In the realm of photocatalysis, carbon-based nanomaterials have drawn more attention in the last ten years. Due to their exceptional and distinct qualities, metal-free carbon-based photocatalytic systems have received a lot of attention recently for their ability to degrade organic contaminants into semiconductor quantum dots, which are already available. A class of nanomaterials with a particle size between 2 and 10 nm showing distinct optoelectrical characteristics is among the variety of catalytic quantum dots. This review covers several synthesis techniques such as electrochemical, laser ablation, microwave radiation, hydrothermal, and optical features of CQDs such as the photoluminescent (PL) property and quantum confinement effect. The uses of CQDs in the degradation of various dyes as well as the difficulties that still exist and the opportunities that lie ahead have also been explored.
