Preparation of heterostructured WO3/TiO2 catalysts from wood fibers and its versatile photodegradation abilities

Abstract A facile route was adopted to synthesize heterostructured WO3/TiO2 photocatalysts from wood fibers through a two-steps hydrothermal method and a calcination process. The prepared WO3/TiO2-wood fibers were used as photocatalysts under UV irradiation for photodegradation of rhodamine B, methy...
