  ABSTRACT: A series of Au/CuOx-TiO2 with various Cu/Ti ratios were prepared. CuOx/TiO2 was prepared by incipient-wetness im- pregnation with aqueous solution of copper nitrate. Au catalysts were prepared by deposition-precipitation method at pH 7 and 338 K. The catalysts were characterized by inductively-coupled plasma-mass spectrometry, temperature pro- gramming reduction, X-ray diffraction, transmission electron microscopy, high-resolution transmission electron mi- croscopy and X-ray photoelectron spectroscopy. The reaction was carried out in a fixed bed reactor with a feed con- taining 1% CO in air at WHSV of 120,000 mL/h·g. High gold dispersion and narrow size distribution was obtained. The addition of CuOx in Au/TiO2 enhanced the activity on CO oxidation significantly. CuOx was in amorphous state which could stabilize the Au nanoparticles. Cu was in Cu1+ state. Cu donated partial electrons to Au. The interactions among Au, Cu1+ and TiO2 account for the high catalytic activity for CO oxidation. The significant promotional effect of CuOx on CO oxidation at low temperature was demonstrated.
