| titleOfInvention | Preparation method of SCR (Selective catalytic reduction) low-temperature denitration catalyst with core-shell structure |
| abstract | The invention discloses a preparation method of an SCR (selective catalytic reduction) low-temperature denitration catalyst with a core-shell structure, and relates to the technical field of production of low-temperature denitration catalysts. The invention comprises ZrO (NO) synthesized by NU-901 assembly 3 ) 2 The powder is calcined for at least 1 hour at the temperature of 250-300 ℃ under the protection of nitrogen, and ZrO (NO) synthesized by NU-901 assembly 3 ) 2 The powder acquisition comprises: to Zr (OBu) 4 Adding 1-propanol and toluene into the n-butanol solution, carrying out ultrasonic treatment, stirring, and heating under vacuum to obtain yellow crystalline zirconium clusters; dispersing crystal zirconium cluster in dimethyl formamide solution, adding acetic acid, stirring, and adding ZrO (NO) modified by polyethylene glycol 3 ) 2 Is injected dissolved inStirring tetracarboxylic pyrene linking agent solution of the dimethylformamide solution, washing with the dimethylformamide solution after stirring, and drying in vacuum to obtain the product; wherein the concentration of the tetracarboxylic pyrene linking agent solution is not less than 1 mg/mL. The invention forms the ZrO (NO) with low-temperature activity assembled and synthesized by NU-901 through low-temperature calcination 3 ) 2 。 |
