Abstract

Hierarchical WO₃ hydrates have been synthesized via an ion exchange method using Na₂WO₄·2H₂O as a precursor. The morphologies and phase structures of WO₃ hydrates can be controlled by tuning the concentration of Na₂WO₄·2H₂O solution. The as-synthesized urchin-like WO₃·0.33H₂O and flower-like WO₃·H₂O possess high specific surface area and numerous adsorption functional groups, such as W [double bond, length as m-dash] O and O–H bonds, on the surface. These characteristics result in excellent adsorption performance for both organic dyes and heavy metal ions from wastewater. The maximum uptake capacities of the urchin-like WO₃·0.33H₂O for methylene blue and Pb²⁺ are 247.3 and 248.9 mg g⁻¹, respectively and those of the flower-like WO₃·H₂O are 117.8 and 315.0 mg g⁻¹, respectively. The formation mechanism of such hierarchical mesoporous urchin-like WO₃·0.33H₂O and adsorption mechanism are studied in this paper.
