1. Introduction Separation induced by kinetic effects has been investigated, using zeolites as a shape selective adsorbent [1]. The control of diffusion process, requiring a precise knowledge of self-, transport and corrected diffusivities (D self , D t and D C , respectively) of molecules inside the nanoporous material, is essential for the design of industrial applications. In the case of str...

The first direct transmission electron microscopic (TEM) observation has been carried out on the continuous monocrystal-thick b-oriented pure silica zeolite MFI films produced by in situ crystallization. The self-supporting film samples for TEM study were fabricated by dissolving the steel substrate with acid. This TEM study is free of those artifacts that are typically associated with TEM samp...

Zeolite-supported single-atom catalysts (SACs) have emerged as a novel class of cheap and tuneable that can exhibit high activity, selectivity stability. In this work, we conduct an extensive screening by means density functional theory calculations to determine the usefulness 3d, 4d 5d transition metal (TM) SACs-supported in MFI-type Silicalite-1 zeolite for CO2 conversion. Two reaction mechan...

– A quadratic network of mutually intersecting channels with single-file confinement is considered as a host system for molecules A undergoing a unidirectional reaction A → B in the channel intersections. If each of the two sets of perpendicular channels is able to accommodate only one of the two types of molecular species, the overall particle concentration deviates significantly from being ho...
