Special Issue Information

Dear Colleagues,

This Special Issue is intended to present studies on the preparation and characterization of controlled functionalized porous materials with tailored properties that can be used in different applications. The functionalization of porous silica materials has been used to tune their physical and chemical properties for different applications, such as drug carriers, gas storage materials, water pollutants adsorbents, or asphalt modifiers. The present Special Issue aims to gather some of the current challenging research explorations in the use of different functional groups, the presence of organic groups within the pores or the amount of a certain functional group which will be attached at the material surface by one or another functionalization procedure, and how all these separate or combined effects will merge together to promote the resulting material for a certain application. The topics of interest include, but are not limited to: the preparation of functionalized porous materials via co-condensation or post-grafting methods; the structural and morphological characterization of these materials with tailored properties; functionalized silica materials for hydrogen, methane, or carbon dioxide storage; functionalized porous silica materials as drug carriers; functionalized mesoporous silica materials used for the removal of dyes, heavy metals, or other pollutants from waste water; and functionalized silica materials used as an asphalt modifier.

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 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. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

The main outcome of this research was to demonstrate the opportunity to obtain a stable and well-ordered structure of MCM-41 synthesized from fly ash. A series of bimetallic (Cu/Mn) catalysts supported at MCM-41 were prepared via grinding method and investigated in catalytic toluene combustion reaction to show the material’s potential application. It was proved, that the Cu/Mn ratio had a crucial effect on the catalytic activity of prepared materials. The best catalytic performance was achieved with sample Cu/Mn(2.5/2.5), for which the temperature of 50% toluene conversion was found to be 300 °C. This value remains in line with the literature reports, for which comparable catalytic activity was attained for 3-fold higher metal loadings. Time-on-stream experiment proved the thermal stability of the investigated catalyst Cu/Mn(2.5/2.5). The obtained results bring a valuable background in the field of fly ash utilization, where fly ash-derived MCM-41 can be considered as efficient and stable support for dispersion of active phase for catalyst preparation.
