The CuO–ZnO/TiO2 catalyst prepared by the ultrasound assisted method demonstrates superior activity in water gas shift reaction in comparison with the catalysts synthesized by incipient wetness impregnation. The sonochemical preparation offers at least two advantages: (1) generation of mesopores on the catalyst surface and (2) doping of Zn into the CuO phase.
