Description

<jats:title>Abstract</jats:title> <jats:p>Environmental degradation and energy shortages are becoming increasingly important as science and technology advance. Here, we review the photocatalytic approach of functionalized carbon quantum dots (CQDs) along with their up-converted photoluminescence behaviour, as well as their photoinduced electron transfer capabilities, opening a new path to effective metal-free photocatalyst. In this article, we are focusing on the recent invention of CQDs and CQD-based photocatalyst for environmental remediation such as dye degradation, CO2 conversion, and water splitting along with the categorization and synthesis of CQDs-derived photocatalysts, and applications for environmental concerns. Although it is essential to incorporate multiple perspectives, since CQDs and CQD-derived photocatalysts have varied perspectives to tackle unique environmental applications, our analysis is expected to offer additional details on CQD synthesis methods, tuning photocatalytic properties of CQDs with surface groups, and the mechanism of degradation of CQDs and CQD-based photocatalysts.</jats:p>
