Special Issue Information

Dear Colleagues,

The scope of this Special Issue can be defined in the broad context of current search for novel catalyst designs to face multiple research challenges in our XXI century society, which include novel biomedical treatments, environmental protection and remediation, alternative and greener energy sources, process intensification in currently defined processes, etc. Great efforts are being currently made in developing hierarchically ordered materials composed of single or multiple-phase materials (i.e., xerogels, supported catalysts, organic–inorganic composites, MOFs, COFs) that can be self-assembled or structured in previously shaped supports (i.e., monoliths, foams, membranes, 3-D-printed customized shapes, and so on).
Herein, we would like to gather a reference collection of publications describing the most recent efforts carried out in the development of novel synthesis strategies, novel deployment of catalytic materials, novel composite configurations, novel theoretical and practical approaches towards the development of 3-D-printed materials, novel configurations of entangled supports and smart distribution of single-active catalytic materials, novel multilayer configurations for photo, electro-catalytic applications, and any fundamental advances in all kinds of catalytic process. Works related to the development of gels for biological studies (i.e., bioorthogonal catalysis) are also welcome.

Impregnation Protocols on Alumina Beads for Controlling the Preparation of Supported Metal Catalysts

Abstract
Whereas the synthesis principles of supported metal catalysts are well documented in the open literature, impregnation protocols on shaped bodies represent sensitive industrial know-how and are, therefore, rarely found. We investigated various synthesis parameters for both wetness (WI) and dry (DI) impregnations to [...] Read more.
Whereas the synthesis principles of supported metal catalysts are well documented in the open literature, impregnation protocols on shaped bodies represent sensitive industrial know-how and are, therefore, rarely found. We investigated various synthesis parameters for both wetness (WI) and dry (DI) impregnations to prepare Pd/γ–Al2O3 alumina beads. Two kinds of catalysts were achieved: homogeneously dispersed catalysts with no metal gradient across the beads and eggshell catalysts. A combination of optical images, Castaing microprobe analysis, elemental analysis, and TEM made it possible to discriminate between catalysts according to their metal loading, location across the bead diameter, and metal dispersion. Regardless of the macropore structure of the alumina beads, we found that volatile solvents (acetone) were preferred for preparing homogeneous catalysts by WI, whereas the use of a viscous aqueous solution (water/glycerol) in DI resulted in an eggshell-type catalyst. The atomic layer deposition (ALD) method was also investigated as a physical vapor phase deposition method for preparing eggshell catalysts. Representative-shaped catalysts were tested for CO oxidation as a model reaction in order to highlight the differences between catalysts with a homogeneous metal distribution (no metal gradient) and eggshell-type.
