Special Issue Information

Dear Colleagues,

Following a seminal publication [1] on polyoxometalate (POM) complexes, research over the years has branched into combinations of inorganic–organic hybrid nanomaterials. More recently, this research has been extended to the combination of POMs into various nanohybrid materials ranging from carbon nanotubules and functionalized graphene to inorganic platforms including MCM-41-type compounds or metal nanoparticles themselves. These compounds have recently been suggested to have scope and application to a wide diversity of areas including nonlinear optics, magnetism, catalysis and health.

Various novel uses have been proposed for such materials including SWCNT–POM nanohybrid materials as electrodes for electrochemical supercapacitors/batteries; Keggin-type POM and Cd(II) semicarbazone Schiff base complexes for excellent adsorption properties for the removal of cationic dye pollutants; efficient visible light-induced O2 generation by self-assembled nanohybrids of inorganic nanosheets and POM nanoclusters; energy storage devices using POM/Graphene nanohybrid materials; water purification by POM-supported ionic liquid phases and micro-encapsulation of POMs inside MCM-41 mesoporous molecular sieve materials which display photoluminescent (incorporating rare earth elements) activity.

As the fields of both polyoxmetalate and nanohybrid material are rapidly advancing, it is our pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are welcome. The main theme can be either on the synthesis and characterization of polyoxometalate nanohybrid materials or on the applications of these compounds, or (ideally) the manuscript can cover both aspects simultaneously.

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. Materials 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 1500 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.

Gold nanoparticles were prepared by sol immobilization (AuSI) or deposition precipitation (AuDP), then deposited on NiO and commercial TiO2 (P25). The Au/NiO catalysts showed higher activity and yield to the secondary amine, compared to Au/TiO2 catalysts, when tested for the reductive amination of benzyl alcohol with isopropylamine. We attribute this result to a synergistic effect between Au and NiO. Moreover, as a result of the protective effect of the polyvinyl alcohol used in the sol immobilization synthesis, the gold nanoparticles on NiO demonstrate an increased resistance to structural changes during the reaction. This effect results in enhanced catalytic efficiency in terms of activity, and better stability against deactivation. Full article

Polyoxometalate (POM) hybrid materials have shown potential as spin-coatable, patternable dielectric thin-films and components for lithographic resists. In particular, the octamolybdate cluster has been shown to possess good spin-coating properties and the patterning capabilities of hybrid octamolybdate thin-films were explored using a combination of broadband UV and electron beam lithography (EBL) techiniques. Dielectric properties of these films were determined by ellipsometry, and octamolybdate clusters were subsequently investigated as negative resists in various blends for potential uses in next-generation photolithography, where contrast, sensitivity, and line edge roughness characteristics were determined. Preliminary evidence for the suppression of the diffusion of photo-generated acids is presented. Full article
