Hierarchical Bi₂WO₆/TiO₂-nanotube composites derived from natural cellulose for visible-light photocatalytic treatment of pollutants.

ABSTRACT: A series of Bi₂WO₆/TiO₂-nanotube (Bi₂WO₆/TiO₂-NT) heterostructured composites were prepared by utilizing natural cellulose (e.g., laboratory filter paper) as the structural template. The obtained nanoarchitectonics, namely Bi₂WO₆/TiO₂-NT nanocomposites, displayed three-dimensionally interwoven structures which replicated the initial cellulose template. The composite Bi₂WO₆/TiO₂-NT nanotubes were formed by TiO₂ nanotubes that uniformly anchored with Bi₂WO₆ nanoparticles of various densities on the surface. The composites exhibited improved photocatalytic activities toward the reduction of Cr(VI) and degradation of rhodamine B un
