Annotation	In this study the definite correlation between textural and structural properties and catalytic performances of platinum- and gold-impregnated TiO2-ZrO2 catalysts in DCM total oxidation has been found. Textural properties, micro/mesoporosity, dispersion of noble metal particles, structural properties and morphology of four laboratory and one commercial catalysts were characterized by nitrogen physisorption at 77, chemisorption, XRD, SEM, TPR and TPD techniques. Besides the initial light-off tests carried out over all the catalysts at high WHSV of 150 dm3gcat-1h-1 also the effect of various WHSV on the catalytic activity and selectivity of platinum and gold-impregnated and calcined TiO2-ZrO2 catalysts was investigated. The durability of all tested catalysts was also studied.
