The influence of metal loading and pH during preparation on the CO oxidation activity of Au/TiO2 catalysts.
Au/TiO2 catalysts with gold loadings in the range 0.06-1.9 wt.%, prepared by 'deposition-precipitation' at pH 9, have a constant and high specific activity for the oxidation of CO: 3.9(+/- 0.4) x 10(-4) molCO s(-1) gAu(-1) at 243 K.
