Zeolite-loaded noble metal catalysts have demonstrated excellent performance in addressing cold-start automotive exhaust NOx emissions and catalytic oxidation of VOCs applications. Pd Pt are the most commonly used active metals PNA VOC catalysts, respectively. However, despite same metal/zeolite composition, efficient sites for been viewed as mainly Pd2+ Pt0, respectively, both which different from each other. As a result, various methods need to be applied dope zeolitic support respectively usages. No matter type species is needed, common requirement that should highly dispersed zeolite stay stable. The purpose this paper review progress synthetic means zeolite-coated (Pd, Pt, etc.) effective or catalysts. To give better understanding relationship between introduced methods, contributed adsorption (PNA) deep were first summarized compared. Then, based on above discussion, detailed construction strategies elaborated terms routes, precursor selection, carrier requirements. It hoped will contribute adsorption/catalysis zeolites provide promising design adsorption/catalysts with high activity, selectivity stability.

Hydrothermal stability is a vital performance criterion considered in the design of heterogeneous metal catalysts for practical applications because widespread presence moisture reaction feeds or products. In this work, we substantially promote hydrothermal Pt-zeolite catalyst by incorporating Sn into zeolite framework. Pt species are stabilized as small nanoparticles, and MFI structure well preserved even after treatment at 850 °C mixed atmosphere (CO + O2 H2O). Adding Pt-MFI not only heals defect sites pure-silica to its structural during but also stabilizes mobile PtOx via Sn–O–Pt interaction. The remarkably high particles encapsulated Sn-promoted reflected CO oxidation which exhibit much higher than nonpromoted catalyst. stabilization effect further extended Pd-MFI average size Pd remains below 2 nm harsh treatments °C.
