| 摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to photocatalytic materials for use in cement. The novel photocatalytic product contains a titanium compound in crystalline phases: CaTiOand/or CaTiO, as well as TiO, integrated with limestone. The product is obtained by reacting limestone with a suitable titanium dioxide precursor in a basic solution, followed by thorough washing of the obtained solid product, drying and calcination at 450-700°C.EFFECT: obtained composite material, which is used as it is or in a mixture with other components, exhibited unexpectedly high photocatalytic activity.17 cl, 6 ex, 4 tbl, 19 dwg |
