Special Issue "Layered Double Hydroxide-Based Catalytic Materials for Sustainable Processes"
Deadline for manuscript submissions: 31 October 2020.
Interests: heterogeneous catalysis; catalytic processes; oxide-based catalysts; catalytic combustion of hydrocarbons and VOCs; light alkanes oxidative dehydrogenation; redox and electronic properties of oxide catalysts
Interests: heterogeneous catalysis; preparation and modification of LDH-type catalysts; mechanochemistry; LDH characterization; catalytic processes; fine chemical synthesis; selective oxidation reactions
Layered double hydroxides (LDHs), also known as two-dimensional anionic clays, as well as the derived materials, including hybrids, nanocomposites, mixed oxides, and supported metals, have been highlighted as outstanding heterogeneous catalysts with unlimited applications in various processes involving both acid-base (addition, alkylation, acylation, decarboxylation, etc.) and redox (oxidation, reduction, dehydrogenation, etc.) mechanisms. This is mainly due to their flexibility in chemical composition allowing finely tuning the nature of the active sites and controlling the balance between them. Additionally, LDHs display a large anion exchange capacity and the possibility to modify their interlayer space, constraining the size and type of reactants entering in the interlamellar space. Further, their easy and economic synthesis, with high levels of purity and efficiency, both at laboratory and industrial scale, make LDH and their derived materials excellent solid catalysts. This Special Issue collects original research papers, reviews, and commentaries focused on the catalytic applications of these remarkable materials.

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. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.

Abstract: 4-Nitrophenol (4-NP) is one of the most common contaminants in industrial waters, since it is used for the synthesis of drugs, fungicides, dyes, explosives, colouring agents for leather, etc., and it is also generated during formulation or degradation of pesticides. In this work we have synthesized a ZnAl-carbonate hydrotalcite by coprecipitation and it has been calcined at 650 ºC in order to obtain a highly dispersed ZnAl mixed oxide. These two phases have been tested for their activity in photocatalytic degradation of 4-nitrophenol. Structural, chemical and textural characterization of the solids has been fully accomplished. The performance of the catalysts in the adsorption and degradation of the contaminant in the dark or under UV-light is compared to that of bulk, commercial, ZnO. The reactions have been followed by means of UV spectra of the aliquots of the suspension of the contaminant taken at different times. The activity of the synthesised solids on the degradation reaction of 4-nitrophenol aqueous solution exceeded that observed with commercial ZnO.
