Abstract

A cetyltrimethylammonium bromide (CTAB) assisted bottom-up route to prepare Bi ₂ WO ₆ fraction-let materials. WO ₃ /Bi ₂ WO ₆ binary hybrid with 2-D structure was designed by a facile hydrothermal process. Subsequently, RGO and g-C ₃ N ₄ nanosheets were incorporated into WO ₃ /Bi ₂ WO ₆ via a cost-effective process. These nano-components of smart materials could simultaneously absorb and degrade contaminants in visible light. Nitroguanidine is an energetic material and harmful to the environment when released into the water. According to the data, NQ is more soluble in water than TNT or RDX, so NQ is more likely to cause water pollution. In this paper, the NQ in wastewater was degraded by using the RGO and g-C ₃ N ₄ doped WO ₃ /Bi ₂ WO ₆ . The results indicated that RGO-WO ₃ /Bi ₂ WO ₆ (R-W-B) and g-C ₃ N ₄ -WO ₃ /Bi ₂ WO ₆ (G-W-B) showed greater degradation rate (0.02731 min ^{− 1} and 0.02462 min ^{− 1} ) as compare to WO ₃ /Bi ₂ WO ₆ (0.0084 min ^{− 1} ). The improved photocatalytic performance of G-W-B or R-W-B accredited to the cascade structure of the synthesized materials. For G-W-B, the holes transferred from WO ₃ to Bi ₂ WO ₆ and then to g-C ₃ N ₄ which prolong the lifetime of photo-generated charges via the valence band potential gradient. The electrons transferred from Bi ₂ WO ₆ to WO ₃ then to RGO for R-W-B.
