Special Issue Information

Dear Colleagues,

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The conversion of syngas (CO + H2) to gasoline-ranged hydrocarbons was carried out using a hybrid catalyst consisting of metal-loaded ZSM-5 coupled with Cu-ZnO in a near-critical n-hexane solvent. Methanol was synthesized from syngas over Cu-ZnO; subsequently, was converted to hydrocarbons through the formation of dimethyl ether (DME) over the metal-loaded ZSM-5. When 0.5 wt% Pd/ZSM-5 and 5 wt% Cu/ZSM-5 among the metal-loaded ZSM-5 catalysts with Pd, Co, Fe or Cu were employed as a portion of the hybrid catalyst, the gasoline-ranged hydrocarbons were selectively produced (the gasoline-ranged hydrocarbons in all hydrocarbons: 59% for the hybrid catalyst with Pd/ZSM-5 and 64% for that with Cu/ZSM-5) with a similar CO conversion during the reaction. An increase in the Cu loading on ZSM-5 resulted in increasing the yield of the gasoline-ranged hydrocarbons, and in decreasing the yield of DME. Furthermore, the hybrid catalyst with Cu/ZSM-5 exhibited no deactivation for 30 h of the reaction. It was revealed that a hybrid catalyst containing Cu/ZSM-5 was efficient in the selective synthesis of gasoline-ranged hydrocarbons from syngas via methanol in the near-critical n-hexane fluid.

Title: Theoretical Investigation on a Novel Two-Step Decomposition of Nitric Oxide over Fe(II) Ion-Exchanged Zeolites Using DFT Calculations

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.
