A luminescent Cobalt(II) co-crystal [Co13(PDC)16(H2O)24.7H2O] 1 (where H2PDC = 2,6-pyridinedicarboxylic acid) have been prepared by oven-heating and slow evaporation of solvent. Single crystal X-ray diffraction (SCXRD) analysis revealed that is a mixture complexes crystallizes in the triclinic space group P-1 geometry around Co(II) ions octahedral. The structure extensively imbued with hydrogen...

• Fe(II) promoted the photo-oxidation of released As(III) in ASS. The mechanism Fe(II)-stimulated was pH-dependent. At pH 3.0, both OH and SO 4 − made a contribution to As oxidation. Reductive sulfur species from ASS played critical role Fe(II)/Fe(III) cycle. Arsenic sulfide sludge (ASS) is typical precipitation product acid smelting wastewater. Previous study reported that when exposed sunligh...

Metal-organic frameworks (MOFs) are promising materials for photocatalytic water splitting reactions, but examples of visible light-responsive, catalytically active, and stable MOFs still rare. A detailed investigation is conducted COK-47 – a recently described MOF comprising 2D Ti-O6 secondary building units (SBUs) toward hydrogen evolution reaction (HER), showing how overall particle morpholo...

In this paper we discuss the newly synthesized binuclear species [Cu2(L(PY18))2(μ1,1-N3)2(N3)2] (1) and [Cu2(L(PY18))2(μ1,3-SCN)2(NCS)2] (2), as obtained from the monometallic precursor [Cu(L(PY18))Br2]. These gemini metallosurfactants incorporate metal/anion cascade cores and are investigated by experimental and theoretical methods. Diagnostic IR stretches support the presence of μ1,1-bridged ...

We investigate the redox, spectroscopy and catalytic reactivity of new cobalt(iii) complexes based on phenolate-rich [N2O3] ligands. These complexes are described as [Co(III)(L(X))MeOH], where X indicates the presence of chloro (), bromo (), iodo (), or tert-butyl () substituents in the 3(rd) and 5(th) positions of each phenolate ring. These substituents modulate the Co(iii) ← PheO(-) LMCT band...

Emission spectroscopy has been used for the first time in a spectroscopic study of a family of uranium(IV) halide complexes in non-aqueous media. The room temperature electronic absorption spectra of the simple coordination compounds [Li(THF)4][UX5(THF)] (X = Cl, Br, I), [Et4N]2[UCl6] and UCl4 in THF have been recorded and all transitions assigned with the aid of a comprehensive computational s...

Multinuclear (1H and 13C) NMR, and Raman spectroscopy, combined with DFT calculations, provide detailed information on the complexation between U(vi) oxoions and 8-hydroxyquinoline-5-sulfonate (8-HQS) in aqueous solution. Over the concentration region studied, U(vi) oxoions (uranyl ions) form one dominant complex with 8-HQS in water in the pH range 3-6, a mononuclear 1 : 2 (metal : ligand) comp...

In this work we undertake the upscaling of a system of partial differential equations describing transport of a dilute N -component electrolyte in a Newtonian solvent through a rigid porous medium. The motion is governed by a small static electric field and a small hydrodynamic force, which allows us to calculate the linear response regime in a way initially proposed by O’Brien. The O’Brien par...
