Solar light assisted photocatalytic degradation of 1,4-dioxane using high temperature stable anatase W-TiO2 nanocomposites

This work outlines a systematic and detailed study of the modification anatase TiO2 with tungsten (W). The impact this coupling has on temperature to rutile phase transition photocatalytic degradation 1,4-dioxane, highly toxic compound that is increasingly present in water bodies also studied. composite photocatalysts 2, 4, 8 16 mol. % W, respectively, were produced using sol-gel process then calcined between 500?1000 °C. crystallinity composition pure W-TiO2 examined X-ray Diffraction (XRD), Raman spectroscopy photoelectron (XPS). All demonstrated 100 crystalline at calcination temperatures as high 800 Due retention 26 after 950 °C, W was established optimum loading for development stable photocatalysts. content significantly impacts activity In presence solar light, 1,4-dioxane successfully degraded by 2-W-TiO2, 4-W-TiO2 8-W-TiO2 photocatalysts, However, increases decreases, only 70 when 900 highest removal achieved both therefore considered sample photocatalysis temperature.
