WO(3)·nH(2)O Crystals with Controllable Morphology/Phase and Their Optical Absorption Properties

[Image: see text] In this work, a one-step hydrothermal route is developed to prepare WO(3)·nH(2)O crystals with various morphology/phases, for which any surfactants, templates, or structure-directing agents are not used. Five types of WO(3)·nH(2)O crystals, including o-WO(3)·H(2)O nanoplates, recta...

description [Image: see text] In this work, a one-step hydrothermal route is developed to prepare WO(3)·nH(2)O crystals with various morphology/phases, for which any surfactants, templates, or structure-directing agents are not used. Five types of WO(3)·nH(2)O crystals, including o-WO(3)·H(2)O nanoplates, rectangular m-WO(3) nanosheets, o-WO(3)·0.33H(2)O microspheres, h-WO(3) nanorods, and bundle-like h-WO(3) hierarchical structures, are successfully obtained by adjusting the amount of H(2)SO(4) and reaction temperature. According to the experimental results, the formation mechanism for various WO(3)·nH(2)O species is proposed. In addition, the optical absorption properties of these WO(3)·nH(2)O crystals are also investigated by UV–vis absorption spectra.
