Abstract
The invention discloses a mesoporous gamma-Fe-Ti-Al2O3 catalyst. The catalyst is prepared from the following raw materials of aluminum isopropoxide C6H21AlO3, glucose C6H12O6.H2O, Fe(NO3)3.9H2O, and tetrabutyl titanate (TBOT) aqueous solution. The invention further discloses a preparation method and application of the mesoporous gamma-Fe-Ti-Al2O3 catalyst. The novel mesoporous gamma-Fe-Ti-Al2O3 catalyst can be applied to catalytic ozonation of ibuprofen and blocking of bromate generation, and has remarkable effect.
Description
technical field [0001] The invention relates to a method for preparing a catalyst, especially a mesoporous γ-Fe-Ti-Al 2 o 3 Catalyst and its preparation method and use. Background technique [0002] The heterogeneous catalytic ozonation technology has the advantages of complete oxidation of organic pollutants, good stability, and the catalyst can be regenerated and reused. It has become a research hotspot in the field of environment in recent years. However, the research on heterogeneous catalyzed ozonation reaction is still in the preliminary stage for water phase reaction. Therefore, it is of great significance to study catalysts for heterogeneously catalyzed ozonation reactions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new mesoporous γ-Fe-Ti-Al 2 o 3 The catalyst can be used to catalyze the ozone oxidation reaction, and can effectively promote the removal of ibuprofen and TOC. [0004] The prese...
