摘要：
Natural clay Bentonite supported ZnWO4 has been successfully synthesized through hydrothermal-thermal decomposition method. The experimental results reveal that 12 wt% of Bentonite supported ZnWO4 exhibited higher photocatalytic activity for the degradation of two basic dyes (Rhodamine-B (Rh-B) and Methylene Blue (MB) under UV light than prepared ZnWO4 Bentonite-ZnWO4 (BZW) was characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), field emission transmission electron microscopy (FE-TEM), X-ray photo electron spectroscopy (XPS), photoluminescence spectroscopy (PL), UV-Vis diffuse reflectance spectroscopy (DRS) and BET surface area analysis. FESEM images exhibit the formation of microflakes, which have been joined together by an edge-to-flat-surface conjunction. From the BET analysis it has been found that BZW has higher surface than prepared ZnWO4. As synthesized Bentonite supported ZnWO4 has high recyclability for four successive cycles.
