Development of nanofibrous membranes incorporating WO3/TiO2/Ag3PO4 photocatalysts for the degradation of methylene blue
In this study, WO3/TiO2 and WO3/TiO2/Ag3PO4 photocatalysts with different ratios were prepared using the sol-gel and precipitation methods. Additionally, to facilitate the recovery of photocatalysts from water, nylon 6,6 nanofiber membranes containing the photocatalysts (NFMWTAP) were fabricated using electrospinning and electrospray techniques. The adsorption and degradation of methylene blue under visible light were compared for different ratios of photocatalysts. The results showed that among the WO3/TiO2 samples with different weight percentages, 3 wt% WO3/TiO2 exhibited the highest methylene blue removal efficiency. Therefore, we synthesized WO3/TiO2/Ag3PO4 ((W/T)-(AP)) photocatalysts with different weight percentages using 3 wt% WO3/TiO2 as the base catalyst. When the ratio of WO3/TiO2 to Ag3PO4 was 5:5, the removal efficiency was the highest, achieving a dye removal rate of 99.60%. Meanwhile, the nylon 6,6 nanofiber membrane containing the photocatalyst achieved a dye removal rate of 99.18% after 30 min of dark adsorption followed by 1 h of visible light irradiation. Even after three cycles of reuse, the dye removal rate remained as high as 97.86%.
