Abstract

Nanocrystalline bismuth tungstat with good visible light response has been synthesized using Pluronic P123 triblock copolymer as surfactant. The prepared samples were characterized by X-ray diffraction, UV-visible spectroscopy, scanning electron microscopy, and BET surface area analysis. The activity of the material in photocatalytic decoloration of aqueous rhodamine B (RhB) solution under visible light was evaluated. The results showed that the presence of P123 could improve the crystallization of Bi2WO6 species and greatly enlarge their specific surface area. The copolymer concentration has a great impact on the bismuth tungstat morphology. The photocatalytic efficiency of the as-prepared Bi2WO6 with P123 adjusted is higher than that of pure Bi2WO6.
