Cu2O nanoparticles are formed by in situ reduction of Cu(OH)2 with Sn2+ ions linked to the surface of the TiO2 precursor. The initial Cu2O nanoparticles serve as seeds for subsequent particle growth. The resulting Cu2O nanoparticles are evenly dispersed on the surface of the TiO2 precursor, and are heat and air stable. The as-prepared composite is an excellent catalyst for Ullmann type cross coupling reactions of aryl halides with phenol. The composite catalyst also showed good stability, remaining highly active after five consecutive runs.
