Abstract

Highly ordered mesoporous WO₃ film was synthesized by employing a template-assisted peroxopolytungstic acid sol–gel method and applied for the first time in gasochromic smart windows. The results demonstrated that this mesoporous microstructured sample with semicrystalline pore walls exhibits excellent performance, including wide optical modulation ability, fast coloring/bleaching response and reliable cyclic stability.
