Abstract

The preparation of mesoporous WO₃ films was carried out by involving of a new nonionic gemini surfactant structure-directing agent. The mesostructured WO₃ films exhibit tridimensional vermicular mesopores, as demonstrated by SAXRD, TEM and N₂ sorption techniques. Compared with the non-templated analogue, the mesoporous tungsten trioxidefilms possess large specific surface area, along with improved electrochemical and electrochromic performances, whose transmittance modulation reached over 60% and coloration efficiency was up to 51.7 cm²•C^－1 at the wavelength of 633 nm.

Key words: mesoporous, tungsten trioxidefilm, cyclic voltammetry, electrochromic
