Ordered three-dimensional (3-D) cage-like mesoporous mixed tungsten–titanium oxides (WO3–TiO2) with relatively high surface area (152 m2g−1) have been synthesized by employing Pluronic F108 triblock copolymer as a structure-directing agent via “acid-base pairs” strategy. Such materials exhibit enhanced electrochromic properties with the contrast ratio (Tb/Tc) of ≈1.8 at 550 nm.
