| titleOfInvention | A kind of nanometer Cu-SSZ-13 molecular sieve and its one-step synthesis method and application |
| abstract | The invention relates to a nano Cu-SSZ-13 molecular sieve, a one-step synthesis method and application thereof, and belongs to the technical field of chemical catalysis. The preparation method of molecular sieve is as follows: dissolving inorganic base in deionized water, then adding aluminum source to obtain solution A; dissolving silicon source in deionized water, then adding first template agent and second template agent to obtain solution B; The source is dissolved in deionized water, and then a complexing agent is added to obtain solution C containing copper complex; solution A and solution B are added to solution C, placed in a hydrothermal reactor for hydrothermal reaction, washed and dried , calcining to obtain Cu-SSZ-13 molecular sieve. The preparation process of the invention not only avoids post-processing steps such as multiple ion exchange and multiple calcination using ammonium salt or copper salt solution, but also overcomes the traditional one-step synthesis method. The problem is that the low-temperature catalytic activity of NO purification in the diesel vehicle exhaust after-treatment system has been improved. |
