Silver-Loaded Carbon and Phosphorous Co-Doped Boron Nitride Quantum Dots (Ag@CP-BNQDs) for Efficient Organic Waste Removal: Theoretical and Experimental Investigations

Abstract

Theoretical results showed that loading of Ag behaves as plasmonic sensitizers and co-catalysts and provides extra bands, which make electron movement easier between valance and conduction bands. The mechanism of the charge separation enhancement was postulated. Our findings might deepen our understanding of how sensitizer surface modification works in photodegradation applications.

Efficient photo-Fenton catalysis using magnetic iron nanoparticles decorated boron nitride quantum dots: theoretical and experimental investigations

“…An XRD pattern was used to measure the crystallinity index (CI), 28,67,68 which was found to be 68.8 for BNQDs before decoration with Fe and 76.6 for Fe@BNQDs. It is worth mentioning that CI was measured from the ratio of the integrated area of all crystalline peaks to the total integrated area under the XRD peaks. The FTIR spectra were characterized to investigate the formation of BNQDs and then the formation of Fe@BNQDs .…”

Recent progress and opportunities in 2D-material quantum dots: synthesis, doping, characterization, and applications

“…The obtained F-doped BNQDs are used to enhance the electrochemiluminescence which can be used as a biosensor [97]. A simple hydrothermal method was incorporated in co-doping the carbon and phosphorous in the boron nitride quantum dots and it was further loaded with silver to form Ag@CP-BNQDs and used in the photocatalytic degradation [98].…”

Impact of Polythiophene ((C4H4S)n; n = 3, 5, 7, 9) Units on the Adsorption, Reactivity, and Photodegradation Mechanism of Tetracycline by Ti-Doped Graphene/Boron Nitride (Ti@GP_BN) Nanocomposite Materials: Insights from Computational Study

“…Having thoroughly explored the literature, several studies have used boron nitride, − graphene, − and titanium alongside other composites − to study the degradation of TC. However, no study was able to integrate polythiophene, titanium, graphene, and boron nitride as optimized in this study.…”
