Membrane and catalysis is a marriage of great scientific interest because, in many cases, the potentialities of membrane processes and those of catalytic processes are enhanced thanks to their synergy. Membrane Catalysis is performed in a device called Membrane Reactor (MR), where the chemical reaction and the separation process can be accomplished simultaneously in the same physical device, thus fulfilling the criteria of process intensification and minimizing environmental and economical impacts. Generally the membrane allows to confine the catalyst in the reaction ambient, thus facilitating its reuse and also permitting the selective separation of specific molecules present in the reaction ambient. As a result, a minimization of the formation of by-products, thus improving conversion, selectivity, and yield that can be obtained. Higher energy efficiency, modularity, and easy scale up are some other advantages of Membrane Catalysis compared to convectional catalysis. The appropriate choice of the membrane type, membrane module configuration, and MR is mainly determined by the type of catalysis (e.g.: homogeneous, heterogeneous, photo, bio) where the membrane can assume many roles as catalyst recovery, separation of the products, rejection of the substrate, etc. In this Special Issue, some of the most recent advances in Membrane Catalysis of basic interest or relevant to current industrial processes or processes under development or of interest for future applications, will be provided to disseminate the latest information for application in various fields.

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. Molecules 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 1800 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.

Abstract: A demonstration unit for hydrogen production via WGS reaction has been designed built and operated for up to 900 hr showing high hydrogen recovery factors, and very low CO concentrations in the permeate side. The produced hydrogen can be directly fed to a PEM FC.

Abstract: The recovery of the valuable intermediate product of reactions in series by a membrane process may avoid the degradation of the product and consequently substantially enhances the yield. This result is obtained only if the dialysis process and the reaction take place concurrently in a so called "integrated process". The photocatalytic reaction here considered produces vanillin by partial oxidation of ferulic acid in a green process. Vanillin is very effectively recovered by dialysis with a non porous poly-ether block amide membrane, thus avoiding its degradation by further oxidation. In fact, the permeation flux of vanillin is much higher than the one obtained with pervaporation. However, also some undesirable behaviors are observed. In fact, also the reagent permeates and concentration polarization limits the permeation rate. The analysis of the experimental results by a mathematical model allows the identification of the procedures, which minimizes these negative effects.
