TiO2 catalytic structure for catalytic processes up to 1000 degC and process for preparing thereof

摘要

In the present invention, there is disclosed a TiOi2 catalytic structure formed by TiOi2 nanoparticles of anatase crystal form containing 0.05 to 5 percent by weight of phosphorus, based on the TiOi2% weight, arranged in circular flat aggregates with specific surface in the range of 40 to 120 me2/g. The invented TiOi2 catalytic structure is suitable for catalytic processes up to the temperature of 800 degC. With morphology of compact particle aggregates having specific surface within the range of 20 to 40 me2/g, the invented TiOi2 catalytic structure is suitable for catalytic processes up to the temperature of 1000 degC. Active substances, being selected from the group consisting of silver, copper, gold, platinum metals, nickel, molybdenum and metal oxides, except for alkali metal oxides, can be applied to both structure types.
