Heterostructured WO3/RGO/protonated g-C3N4 three-layer nanosheets for enhanced visible-light photocatalytic activity
Source abstract
Abstract
Abstract The novel WO3/RGO/protonated g-C3N4 (PCN) composites with a 2D/2D/2D architecture were successfully prepared through a microwave-assisted hydrothermal method. The 2D/2D/2D heterojunction exhibited a short charge migration path and a wide interface contact area, which could produce a large number of intimate high-speed charge transfer channels and enhance bulk-to-surface and interfacial charge transfer abilities. The WO3/RGO/PCN composites displayed dramatically improved photodegradation performance for tetracycline hydrochloride (TC-HCL) under illuminating of visible light as compared to PCN, WO3, as well as binary RGO/PCN and WO3/PCN heterojunctions. The photocatalytic mechanism was confirmed by photoluminescence spectra (PL), photocurrent response, electron spin resonance spectra (ESR) and electrochemical impedance spectroscopy (EIS). The synergistic effect of 2D/2D/2D architecture and Z-Scheme electron migration mechanism greatly boosts the migration and separation of photoexcited charge carriers that leads to the enhanced photodegradation activity.
