Exploring the potential of carbon quantum dots (CQDs) as an advanced nanomaterial for effective sensing and extraction of toxic pollutants

Abstract

Both organic and inorganic pollutants seriously impact the environment, human health, and ecosystems. Carbon quantum dots (CQDs) and their composites have emerged as promising materials for addressing these environmental issues due to their adaptability, efficiency, and environmentally friendly nature. This study aims to discuss the most recent developments in CQDs-based nanomaterials, focusing on their distinctive structures, synthesis methodologies, characterizations, and applications in environmental science as pollutants extractors and sensors. It studies the potential of nanomaterials based on CQDs for identifying and absorbing contaminants, focusing on their effectiveness in detecting and absorbing hazardous organic chemicals and heavy metals from different environments. The key results include the recognition of distinctive surface characteristics of CQDs-based nanomaterials, which facilitate effective interactions with various pollutants. This enhances their effectiveness in sensor applications and as constituents of extraction materials. This review emphasizes the potential of CQDs-based nanomaterials to transform pollution detection and extraction practices by providing an extensive overview of their utility in environmental science.
