Luminescent Carbon Dots for Environmental Photocatalytic

Abstract

Innovative materials based on different natural sources with enhanced luminescence propertyare called carbon dots. Different synthesis methods of these incredible nanomaterials are changing their property. The photocatalytic potential of the carbon dots has a solution for wastewater treatment. Important characterizations to determine carbon dots' features Are low cost, biocompatible, facile synthesis, high-quantum yield (QY) nanomaterial, namely carbon dot. In regard to the scenario in which the proliferation of waste in waters caused by anthropogenic activities and natural disasters has become a primary global concern because of severe health and environmental harms, the search for new materials that provide eradication of waste present in water is a great challenge. In this sense, nanomaterials arising from natural sources is an incredible alternative, as the carbon dots. Many types of carbon dots were anaalyzed in the literature, as these nanomaterials have considerable potential for many purposes, including the photocatalytic process of organic and inorganic materials in water because they are low cost and biocompatible, which makes them eco-friendly materials to apply in water treatment. In this overview, we presented various researches that demonstrated different carbon dots syntheses, an extensive characterization by many techniques, and the photocatalytic process was reported based on different models, as different precursors, methodologies of syntheses, which changes all photodegradation results. Based on the literature, we have also demonstrated that these nanomaterials exhibit an incredible potential for photodegradation of diversity of organic materials, including benzene, pesticides, phenol and methylene blue, and others, in water, indicating their promising solution of low cost, biocompatible, photocatalytic nanomaterial for wastewater treatment. Finally, this overview shows that these luminescent materials presented the incredible potential of use in wastewater treatment.
