摘要：

The development of a method for making an adherent coating of Au/TiO2 on a cordierite monolith is described. The optimum method entails first forming a wash-coat of TiO2 by combining a colloidal dispersion of TiO2 with Degussa P-25 TiO2 that has been washed, dried and crushed. Subsequent deposition of gold from HAuCl4 solution at pH 9 resulted in a catalyst that was less active for the oxidation of carbon monoxide than a similar preparation using only P-25, but reproducible values of T-50 of about 250 K were obtained.
