Here we report a direct synthesis of a mesoporous TiO2-RuO2 composite. Titanium tetraisopropoxide (TTIP) and RuCl3 are used as inorganic precursors for TiO2 and RuO2, respectively. Evaporation-induced assembly of spherical micelles made of an asymmetric poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) triblock copolymer enables the fabrication of a mesoporous TiO2-RuO2 composite with a uniform pore size of 30 nm.
