Special Issue "Metal-Loaded Zeolite Catalysts"
A special issue of Catalysts (ISSN 2073-4344).
Deadline for manuscript submissions: closed (15 January 2014)
Zeolites are known to be capable of supporting active metals such as Pt, Pd, Cu, Ni, etc. They are also extremely well known in the chemical process industries as highly suitable from a processing, regeneration, and handling perspective for large-scale catalysis operations. Indeed, numerous cracking, isomerization, and other processes rely primarily on zeolitic acid catalysis for industrial application.
The marriage of shape-selective catalysis with metal activity through the use of zeolites seems a perfect fit. Yet only a very few such examples that have found industrial application exist. Two such systems that come to mind are Pt/K-L aromatization and Ga/H-MFI light paraffin aromatization catalysts, but even these two well-known systems have found only short-lived rather than widely accepted industrial application. Cu and Fe on MFI catalysts have shown promise as replacements for expensive Pd and Pt automotive emission catalysts, yet none have achieved the demanding properties required for actual application. Many other such examples are known.
This issue invites contributions dealing with metal-loaded zeolites including methods for preparation and activation, deactivation, and stability. Comments regarding the issues surrounding industrial application are especially welcome.

Abstract: Previous works done by many researchers on this topic are all related to catalysis under certain, steady-state conditions. Our approach is proposed in the way of two-step direct decomposition of NO; first, concentration of NO in micropores of zeolite at ambient temperature, using Fe(II), an affinity site for NO; and then, decomposition of adsorbed and concentrated NO by an activation energy given. We found in the process of this study that this methodology is quite unique and well-resemble to the function of a reductase P450nor. In this article, we will propose that the process can be attained theoretically. Simultaneously, we are doing now the catalytic activity tests, which will be published elsewhere in the closest future.
