Special Issue Information

Dear Colleagues,

The success of engineering functional, efficient, sustainable, and environmentally-benign materials for applications is driven by many scientific, technological, economic, and societal reasons. Fundamentally transformative discoveries are needed to advance the industrial production of fine chemicals, pharmaceuticals, fuels, and molecules for other needs, accordingly. One such route to achieve such transformations is in the discovery and synthesis/manufacture of next-generation metallic composite materials for applications in catalytic processes.  This new special issue, ‘Metallic Materials and Composites as Catalysts’ for the journal Metals specifically focuses on such advances in the field.

Accordingly, I am pleased to invite your participation to the Special Issue ‘Metallic Materials and Composites as Catalysts’ for the journal Metals. For this issue, we specifically seek new research papers that report and discuss the synthesis, manufacture, or utilization of metallic composite materials in various catalytic roles such as heterogeneous, electrocatalysis, or photocatalysis. New research papers from experiment, theory, or both are welcome , and the specific reactions to be catalyzed are open to all areas, however particular emphasis may be given to reactions that provide exceptionally high societal benefit (CO2 mitigation to fuels, etc). Metallic/composite systems of most interest to this edition could include hybrid metal/inorganic supported catalysts, engineered or doped low-dimensional carbon, compositionally-modified nanoporous frameworks, amorphous metal/metal oxides, and more.  We are eager to welcome your contributions in these areas and appreciate your dedication to helping advance research in this burgeoning area.

Dr. Rees B. Rankin

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 submissions that pass pre-check are 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. Metals 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 2600 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.

Hydrogenation of bulky aromatic hydrocarbons is an important problem to be solved in order to improve the quality of fuels. Pd-containing catalysts modified by strong acids have been prepared and studied by diffuse-reflectance IR spectroscopy, and the catalytic activity of the materials has been determined. In studying the selective liquid-phase hydrogenation of sec-butylbenzene as a model substrate, it was shown that modification of Pd/Al2O3 catalysts with acid additives (H2SO4 or H2WO4) results in a significant increase in the hydrogenation activity and selectivity. IR spectroscopy of adsorbed CO and d3-acetonitrile revealed that larger palladium metal particles are formed on the Pd-H2SO4(H2WO4)/Al2O3 catalysts, with ionic states of palladium being present even in the samples reduced in H2.
