Special Issue Information

Dear Colleagues,

In recent years, environmental and economic concerns have raised strong attention to restyling important industrial processes, so that the use of harmful substances and the generation of toxic waste could be avoided. In this regard, there is no doubt that the development of innovative materials for the improvement of catalytic heterogeneous processes can play a fundamental role in the optimization of environmentally-friendly technologies by substitution, for instance, of liquid acid catalysts by solid materials. Since their discovery, in the early 1990s, ordered mesoporous materials opened the door for new catalytic applications, based partially on novel principles, owing to their extraordinary intrinsic features, stimulating interest in materials with novel framework topologies and a pore architecture. This Special Issue on “Catalysis with Mesoporous Materials” is a suitable approach to discuss the recent progress in the field of ordered mesoporous materials. The articles presented in this Special Issue will cover various topics, ranging from different techniques for the synthesis and morphological modification of mesoporous materials, to the preparation of catalytic systems, and their application in several areas of interest, such as in acid catalytic processes, redox processes, and photochemical and sensing applications. Therefore, this Special Issue welcomes contributions from all researchers working on mesoporous materials, as well as on their characterization, properties, and applications.

The Special Issue will cover, but will not be limited to, the following topics:

  • New syntheses of mesoporous materials;
  • Techniques of morphology modification;
  • Highly dispersed heteroatoms and oxidic species;
  • Highly dispersed metal-, metal oxide-, or metal sulfide-nanoparticles;
  • Anchoring of molecular active species to the surface;
  • Ordered mesoporous materials in catalysis;
  • Grafted active sites and their characterization;
  • Mesoporosity and biological materials;
  • Acid-base reactions for chemical synthesis;
  • Functionalized mesoporous materials as suitable catalysts;
  • Mesoporous supports;
  • Redox catalysis with mesoporous systems;
  • Catalysis by supported nanoparticles materials;
  • Photochemical properties and applications of mesoporous materials;
  • Electrochemical and optical properties on ordered mesoporous materials;
  • Mesoporous materials in sensing.

It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are welcome.

Ferrierite and Its Delaminated Forms Modified with Copper as Effective Catalysts for NH3-SCO Process

Ferrierites and their delaminated forms (ITQ-6), containing aluminum or titanium in the zeolite framework, were synthetized and modified with copper by an ion-exchange method. The obtained samples were characterized with respect to their chemical composition (ICP-OES), structure (XRD, UV-Vis DRS), textural parameters (N2-sorption), surface acidity (NH3-TPD), form and reducibility of deposited copper species (UV-Vis DRS and H2-TPR). Ferrierites and delaminated ITQ-6 zeolites modified with copper were studied as catalysts for the selective catalytic oxidation of ammonia to dinitrogen (NH3-SCO). It was shown that aggregated copper oxide species, which were preferentially formed on Ti-zeolites, were catalytically active in direct low-temperature ammonia oxidation to NO, while copper introduced into Al-zeolites was present mainly in the form of monomeric copper cations catalytically active in selective reduction of NO by ammonia to dinitrogen. It was postulated that ammonia oxidation in the presence of the studied catalysts proceeds according to the internal-selective catalytic reduction mechanism (i-SCR) and therefore the suitable ratio between aggregated copper oxide species and monomeric copper cations is necessary to obtain active and selective catalysts for the NH3-SCO process. Cu/Al-ITQ-6 presented the best catalytic properties possibly due to the most optimal ratio of these copper species. Full article

Hierarchically porous ZSM-5 was prepared by utilizing a two-step crystallization procedure with carbon–silica composites as precursors. The hierarchically porous zeolites obtained a regular mesoporous structure with aluminum incorporated into the carbon–silica composite frameworks. The carbon–silica composite zeolites were characterized by XRD, TEM, SEM, and nitrogen adsorption/desorption. As-prepared hierarchical zeolites were used in the 1,3,5-triisopropylbenzene (TIPB) cracking reaction and exhibited significantly high TIPB conversion, while the accessibility factors were also determined.
