Multifunctional heterogeneous catalysts: Tetrakis (pentafluorophenyl)porphinato]iron(III) immobilized on amine-functionalized Diatomaceous Earth for catalytic and adsorption applications
(Elsevier, 2023)
Artículo / Artikulua,
The use of Diatomaceous Earth (DE) as a promising support of a synthetic metalloporphyrin is reported, trying to
heterogenize metalloporphyrin catalysts to mimicking enzyme site isolation and improving reaction selectivity.

Optimization of hydrocalumite preparation under microwave irradiation for recovering aluminium from a saline slag
(Elsevier, 2021)
Artículo / Artikulua,
Aluminium was successfully extracted by treating an aluminium slag with aqueous NaOH under reflux conditions. This solution was purified by precipitation of silicon species by addition of HCl up to pH = 1, and used for ...
Inorganic–organic hybrids based on sepiolite as efficient adsorbents of caffeine and glyphosate pollutants
(Elsevier, 2020)
Artículo / Artikulua,
Sepiolite clay mineral was functionalized with (3-chloropropyl)triethoxysilane (ClPTES) or 3-[tri(ethoxy/methoxy)silyl] propylurea (TEMSPU) alkoxides and tested as adsorbent for herbicide glyphosate and also of caffeine, ...
M(II)-Al-Fe layered double hydroxides synthesized from aluminum saline slag wastes and catalytic performance on cyclooctene oxidation
(Elsevier, 2022)
info:eu-repo/semantics/article,
Aluminum was extracted from saline slags via an alkaline method and employed in the synthesis of Layered Double Hydroxides (LDH) with various M2+ cations (Co, Mg, Ni and Zn), while Al and Fe were the M3+ cations, using the ...
Preparation of Al/Fe-PILC clay catalysts from concentrated precursors: enhanced hydrolysis of pillaring metals and intercalation
(Royal Society of Chemistry, 2020)
info:eu-repo/semantics/article,
The modification of bentonite with Al-Fe species from different concentrated precursors at both stages: (i) the preparation of the (Al/Fe)-mixed pillaring solution and (ii) intercalation itself, was studied at lab scale. ...
Zn-Ti-Al layered double hydroxides synthesized from aluminum saline slag wastes as efficient drug adsorbents
(Elsevier, 2020)
info:eu-repo/semantics/article,
This work reports the synthesis of Zinc-Titanium-Aluminum (ZnTiAl) layered double hydroxides (LDH) with various proportions of Al[sbnd]Ti and a Zn/(Al[sbnd]Ti) molar ratio of 3:1 by the co-precipitation method. Two series, ...
Progress and perspectives on pillared clays applied in energetic and environmental remediation processes
(Elsevier, 2020)
info:eu-repo/semantics/article,
Pillared interlayered clays (PILCs) are materials that show a two-dimensional layered porous structure with properties that could be interesting alternatives to zeolites and other microporous solids. Some of the properties ...
Application of industrial wastes from chemically treated aluminum saline slags as adsorbents
(American Chemical Society, 2018)
info:eu-repo/semantics/article,
In this study, industrial wastes, which remain after aluminum extraction from saline slags, were used as adsorbents. The aluminum saline slags were treated under reflux with 2 mol/dm3 aqueous solutions of NaOH, H2SO4, and ...
Effective degradation of methylene blue in aqueous solution using Pd-supported Cu-doped Ti-pillared montmorillonite catalyst
(Elsevier, 2019)
info:eu-repo/semantics/article,
The effluents from the textile, paper and food industries contain organic dyes that are strongly colored and reveal harmful effect on living systems. In order to reduce water pollution, the degradation of dye into non toxic ...
Photocatalytic degradation of trimethoprim on doped Ti-pillared montmorillonite
(Elsevier, 2019)
info:eu-repo/semantics/article,
Montmorillonite pillared with titanium and doped with Cr3+ or Fe3+ has been tested for the photo-degradation of the antibiotic trimethoprim (trimethoxybenzyl-2,4-pyrimidinediamine) under different conditions, namely, in ...
