| 英文摘要: |
| CHA molecular sieve is the most promising carrier material for NOx emission control of diesel vehicles due to its large specific surface area, developed pore structure, and adjustable acidity. Based on the analysis of more than 50 articles, the research progress of CHA molecular sieve in PNA and SCR catalytic materials for diesel vehicles in the past 20 years was reviewed. The effects of active components, molecular sieve structure properties, and gas components on the performance of the catalyst were described. The research direction of CHA molecular sieve was prospected. |
