Photocatalysis plays a vital role in addressing environmental remediation and energy generation. Carbon quantum dots (CQDs) represent superior category of photocatalysts devoid metals, boasting remarkable electron transfer capabilities, up-conversion photoluminescence, non-toxic properties. Notably, CQDs can function independently as or become part composite photocatalytic materials. This article explores the precursor materials used CQD production various methods for preparing enhanced with CQDs, such hydrothermal, solvothermal, microwave, chemical oxidation, etc. Furthermore, we provide an extensive overview recent advancements pristine, doped, CQD-based photocatalysts, encompassing applications like organic pollutant degradation water, hydrogen production, CO2 photoreduction fuel The effect surface computational modelling was also addressed.
