Abstract：
Enhancing surface area is one of the efficient ways to improve photochromic sensitivity of WO3 center dot 0.33H(2)O. Hierarchical WO3 center dot 0.33H(2)O mesoporous nanorod assemblies were synthesized via proton exchange by adjusting the concentration of Na2WO4 center dot 2H(2)O. When the concentration of Na2WO4 center dot 2H(2)O is 2.0 g L-1, mesoporous nanorods with 10 similar to 20 nm in diameter and an average pores size of about 4 nm were obtained. The novel WO3 center dot 0.33H(2)O porous structure possesses highly photochromic sensitivity and fatigue resistance properties. It exhibits visible-light-driven photochromic response due to large specific surface area originated from the mesoporous structure. The formation of mesopores is due to the volume decreasing in the transformation process from WO3 center dot H2O to WO3 center dot 0.33H(2)O. (c) 2012 Elsevier B.V. All rights reserved.
