Molybdenum (VI)‐oxo Clusters Incorporation Activates g‐C₃N₄ with Simultaneously Regulating Charge Transfer and Reaction Centers for Boosting Photocatalytic Performance

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 32(38)

Published: July 7, 2022

Abstract Establishing local built‐in electric field of 2D semiconductors is one the promising strategies to regulate oriented charge delivery active centers for enhancing photocatalytic performance. Herein, a novel heptamolybdate polyanions‐intercalated porous g‐C 3 N 4 ([Mo 7 O 24 ] 6− ‐ p CN) catalyst with integrating highly desirable visible‐light features reported. After intercalation, apparent reaction rate constants ( k app ) [Mo CN bisphenol A (BPA) and 4‐chlorophenol (4‐CP) photodegradation are remarkably enhanced, which 9.0 6.4 times faster than those CN, respectively. Analogously, values 6– ‐CN BPA 4‐CP removal also improved by contrast CN. The experimental results density functional theory calculations indicate that formed in polarization direction from aromatic rings inserted clusters. Driven field, photogenerated carriers can be efficiently separated better reactive oxidative species (ROSs) production. These atoms proved as adsorption sites phenols, greatly reducing migration distance ROSs thus improving performances. This work offers reliable strategy construct via polyoxometalates intercalation effective solar energy conversion phenolic wastewater remediation.

Copper tungstate (CuWO4)/graphene quantum dots (GQDs) composite photocatalyst for enhanced degradation of phenol under visible light irradiation

Results in Physics, Journal Year: 2023, Volume and Issue: 45, P. 106253 - 106253

Published: Feb. 1, 2023

Photocatalysis is one of the most preferred methods for degradation organic pollutants as it can lead to complete mineralization employing sunlight an energy source. Until so far enormous number investigations have been done regarding development visible light responsive, stable, and cost effective photocatalysts. In present work, owing objectives mentioned above, attempt was made develop efficient, cheaper, active composite photocatalyst consisting moderate band gap, CuWO4 with electron conductive graphene quantum dots. A series photocatalysts prepared by varying amount while keeping GQDs fixed, their activity evaluated phenol under irradiation. The were characterized using X-ray diffraction (XRD), Scanning microscopy (SEM), Raman spectroscopy, Fourier Transform Infrared (FTIR) Photoluminescence (PL) evaluation crystallinity, functional groups, properties charge carrier separation, respectively. maximum efficiency photodegradation simulated wastewater achieved sample 0.5GCW (optimized having 0.5 wt% respect fixed GQDs), 53.41%, compared pure sample, which exhibited 19.08% efficiency. possible mechanism enhanced proposed mainly due efficient transfer electrons from results show that dots significantly contributes improvement photocatalytic performance.
