The catalytic structure of TiO 2, formed by the TiO 2. % with anatase crystalline form, containing 0.05 to 5 wt. % phosphorus, based on the weight of TiO 2, organized in circular surface aggregates, having a specific surface area of 40 to 120 m 2 / g, is suitable for catalytic processes up to 800 degC. With compact particle aggregate morphology, with a specific surface area of 20 to 40 m.sup.2 / g, it is suitable for catalytic processes up to 1000 degC. Active substances selected from the group consisting of silver, copper, gold, platinum metals, nickel, molybdenum and metal oxides with the exception of alkali metal oxide can be applied to both types of structures. |
