Abstract
This chapter has discussed the preparation of micrometer-sized spherical particles of bismuth tungstate (Bi2WO6) with the hierarchical architecture of “flake-ball” shape for photocatalytic application. The particles, which are assemblies of polycrystalline flakes composed of square-shaped laminar plates with a lateral size of a few hundred nanometers and thickness of 20–35 nm, are prepared by a facile hydrothermal reaction without using any surfactants and polymers as structure-directing agents. An excess amount of a tungstate precursor (10 %) and an acidic condition (pH 1.2) during the hydrothermal reaction are required to obtain a high yield of uniform particles with the flake-ball architecture. The control of the hierarchical assemblies of two-dimensional nanostructures provides high crystallinity, large surface area (19 m2 g−1), and large pore volume. The flake-ball particles are promising as a photocatalyst for oxidative decomposition of organic pollutants to carbon dioxide, for example, in water purification systems because of the high level of photocatalytic activity, the response to visible light, and feasible separation from suspensions by sedimentation and filtration.
