✦ Synopsis

Pt-doped and SnO,-ternplated TiO, can be prepared by sol-gel methods and are very active in CO oxidation especially at low PC0 and high 0,:CO ratios. It may also have activity in CO oxidation promoted by water vapour at moderate temperatures of reaction. Scanning calorimetry and residual gas analysis suggest that 0 finds it relatively difficult to establish itself on a surface precovered with CO and it may be that water-generated OH groups at the F't-oxide interface accelerate this particular process.
