In this paper, AgI was successfully synthesized in the presence of WO3 to form AgI/WO3 Z scheme hetero-junction by solid-phase heating method and by varying the WO3 mole ratio (1:0.5, 1:1, 1:2 and 1:3) with respect to the AgI. The PL spectra indicate that the introduction of WO3 to AgI can efficiently suppress the recombination of photo-generated charge carrier. The photocatalytic activity of WO3/AgI was investigated under visible light by using the Amoxicillin (AMX) antibiotic as an organic target in aqueous solution. The WO3/AgI photoactivity for AXM was greatly enhanced when both materials were coupled to form a Z-scheme system. The highest degradation percentage was reached using the WO3/AgI material ratio mole of 1/1. As compared with to the pure WO3 and AgI, the WO3/AgI hybrid material show remarkably improved visible-induced photocatalytic activities in degrading AMX for the enhanced transport ability of electrons and holes.
Novel g-C3N4/InVO4 materials were synthesized by a fabricated via hydrothermal and heating methods. The physicochemical properties of the photocatalysts were investigated by X-ray diffraction (XRD), infrared spectroscopy (IR), Photoluminescence spectroscopy (PL), UV-Vis diffuse reflectance spectroscopy (UV-Vis-DRS) and Energy dispersive X-ray spectroscopy (EDX). The photocatalytic performances were evaluated by degradation of tetracycline (TC). The g-C3N4/InVO4 composite at a weight ratio of 10 % exhibited the most excellent photocatalytic activity for TC degradation under visible irradiation which was more active than that of pure components.
WO3/Ag3VO4photocatalyst was synthesized for benefiting the visible region of solar spectrum for degradation of antibiotic pollutant. The prepared catalyst was characterized by using scanning electron microscope (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR) and energy-dispersive X-ray spectroscopy (EDX). The photocatalytic performance of material was evaluated by the photoredution of degradation of Amoxicillin (AMX) antibiotic under visible light. Results show that the obtained WO3/Ag3VO4photocatalyst can significantly enhance photocatalytic activity in comparison with the pure WO3 and Ag3VO4. The enhanced photocatalytic activity of WO3/Ag3VO4 was predominantly attributed to the synergistic effect which increased visible-light absorption and facilitated the efficient separation of photoinduced electrons and holes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
