CeO2 nanoparticles were coated with polydopamine (PDA) by dopamine polymerization in water dispersions of CeO2 and characterized by Infrared and Near Edge X-ray Absorption Fine Structure spectroscopy, Transmission Electron Microscopy, Thermogravimetric analysis and X-ray diffraction. The resulting materials (PDAx@CeO2, with x = PDA wt% = 10, 25, 50...

We report a novel synthetic procedure for the high-yield synthesis of metal–organic frameworks (MOFs) with fcu topology with a UiO-66-like structure starting from a range of commercial ZrIV precursors and various substituted dicarboxylic linkers. The syntheses are carried out by grinding in a ball mill the starting reagents, namely, Zr salts and th...

Article
We report on the results of an in situ synchrotron powder X‐ray diffraction study of the crystallisation in aqueous medium of two recently discovered perfluorinated Ce(IV)‐based metal‐organic frameworks (MOFs), analogues of the already well investigated Zr(IV)‐based UiO‐66 and MIL‐140A, namely, F4_UiO‐66(Ce) and F4_MIL‐140A(Ce). The two MOFs were o...

We report on the results of a thorough in situ synchrotron powder X-ray diffraction study of the crystallisation in aqueous medium of two recently discovered perfluorinated Ce(IV)-based metal-organic frameworks (MOFs), analogues of the already well investigated Zr(IV)-based UiO-66 and MIL-140A, namely, F4_UiO-66(Ce) and F4_MIL-140A(Ce).

Article
Metal–organic frameworks (MOFs) have gained widespread attention due to their modular construction that allows the tuning of their properties. Within this vast class of compounds, metal carboxylates containing tri- and tetravalent metal ions have been in the focus of many studies due to their often high thermal and chemical stabilities. Cerium has...
Article
The development of efficient water oxidation catalysts (WOCs) is of key importance in order to drive sustainable reductive processes aimed at producing renewable fuels. Herein, two novel dinuclear complexes, [(Cp*Ir)2(μ-κ³-O,N,O-H4-EDTMP)] (Ir-H4-EDTMP, H4-EDTMP⁴⁻ = ethylenediamine tetra(methylene phosphonate)) and [(Cp*Ir)2(μ-κ³-O,N,O-EDTA)] (Ir-E...

The present review aims to highlight the potential of an emerging 2D single element material: phosphorene. Attention is focused on the more recent studies on phosphorene, in terms of synthetic approaches, modification aimed at its stabilization, and potential applications in the biomedical field. Critical aspects for a practical use of phosphorene...
Article
A near solvent-free synthetic route for Ce-UiO-66 metal-organic frameworks (MOFs) is presented. The MOFs are obtained by simply grinding the reagents, cerium ammonium nitrate (CAN) and the carboxylic linkers, in a mortar for few minutes with the addition of a small amount of acetic acid (AcOH) as modulator (8.75 eq, o.5 mL). The slurry is then tran...

Surface modified CeO2 nanoparticles were prepared by reacting nanometric CeO2 with a fluoroalkyl (C8F17-C2H4-PO(OH)2) or a fluorobenzyl phosphonic acid (C6F5-CH2-PO(OH)2). Both non-modified and fluorophosphonic acid modified CeO2 were used as fillers of composite Aquivion membranes, with loadings up to 5 wt%. Ex situ accelerated ageing using the Fe...
Article
Reaction of cerium ammonium nitrate and tetrafluoroterephthalic acid in water afforded two new metal-organic frameworks with UiO-66 [F4_UiO-66(Ce)] and MIL-140 [F4_MIL-140A(Ce)] topologies. The two compounds can be obtained in the same experimental conditions, just by varying the amount of acetic acid used as crystallization modulator in the synthe...

Mixed Membrane Matrices (MMMs) made up with Nafion and nanocrystals of zirconium MOF UiO-66 or the analogous sulfonated SO3H-UiO-66 were prepared by varying the filler loading and the size of the crystals. The combined effects of size and loading, together with the presence of sulfonic groups covalently linked to the MOFs, were studied with regard...
Article
The formation of layered zirconium phosphate phenylphosphonates, Zr(O3POH)2−x(O3PC6H5)x (hereafter ZP(PP)x, with x in the range 0–2.0) from precursor solutions of zirconyl propionate, phosphoric and/or phenylphosphonic acids was studied by using NMP as solvent. On the basis of this investigation, composite membranes made of a SPEEK matrix (EW = 625...
Article
Single phase mixed zirconium phosphate phenylphosphonates, ZrP(PP)x, were prepared by two different synthetic approaches: reaction of gels of nanosized α-zirconium phosphate in propanol with solutions of phenylphosphonic acid (H2PP), leading to the topotactic exchange of monohydrogen phosphate groups with phenylphosphonate groups, and precipitation...
