Project summary:
Metal nanoparticles immobilized at zeolite supports are important class of heterogenous catalysts for hydrogenation and dehydrogenation, reforming, and water-gas shift reactions. Zeolites, porous elementosilicates, are used to encapsulate metal nanoparticles to improve their stability. Currently, in-situ encapsulation and post-synthesis functionalization are two main synthesis strategies for metal incorporation … more

Zeolites are porous elementosilicates with vast applications in the fields of catalysis, sorption, and ion-exchange. Their advantage lies in properties, such as high adsorption capacity, defined microporosity (resulting in molecular sieving effect), adjustable chemical composition, and possibility for post-synthesis modifications. Conventional synthesis of zeolites uses solvothermal methods that are limited … more
