A Review on Carbon Quantum Dots Modified g-C3N4-Based Photocatalysts and Potential Application in Wastewater Treatment

Carbon quantum dots (CDs) are a fascinating class of carbon nanomaterials (less than 10 nm in size) with unique optical, electrical, and physicochemical properties. In addition to these properties, CQDs exhibit the desired advantages aqueous stability, low toxicity, high surface area, economic feasibility, chemical inertness, highly tunable photoluminescence behaviour. Recently, graphitic nitride (g-C3N4) has appeared as one required stable carbon-based polymers due its varied applications several fields. this regard, modification strategies have been made g-C3N4 semiconductor using enhance adsorptive photocatalytic activity. comparison other dots, shows strong fluorescent such wide excitation spectra, photostability, photo-luminescent emission spectra. The interaction inside multicomponent photocatalyst further promotes activity by improving charge transference, which plays vital role electrochemistry. Therefore, auspicious field photocatalysis, wastewater treatment water adsorption treatment. This particular article featured recent progression CDs/g-C3N4-based photocatalysts focusing on their luminescent mechanism potential
