Direct synthesis of a mesoporous TiO2–RuO2 composite through evaporation-induced polymeric micelle assembly

Abstract

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.
