A nonconventional aluminum source in the production of alumina-pillared clays for the removal of organic pollutants by adsorption
(Elsevier, 2021)
Artículo / Artikulua,
This study is the first to propose the use of aluminum saline slag as aluminum source in the synthesis of alumina pillared clays (Al-PILC). Aluminum was extracted from this waste using both alkaline and acid solutions and ...
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, ...
Hydrothermal liquefaction of biomass as one of the most promising alternatives for the synthesis of advanced liquid biofuels: a review
(MDPI, 2021)
info:eu-repo/semantics/article,
The use of biofuels offers advantages over existing fuels because they come from renewable sources, they are biodegradable, their storage and transport are safer, and their emissions into the atmosphere are lower. Biomass ...
Effect of high pressure on the reducibility and dispersion of the active phase of Fischer-Tropsch catalysts
(MDPI, 2019)
info:eu-repo/semantics/article,
The effect of high pressure on the reducibility and dispersion of oxides of Co and Fe supported on -Al2O3, SiO2, and TiO2 has been studied. The catalysts, having a nominal metal content of 10 wt.%, were prepared by incipient ...
A comparative study of the catalytic performance of nickel supported on a hibonite-type La-hexaaluminate synthesized from aluminum saline slags in the dry reforming of methane
(Elsevier, 2022)
Artículo / Artikulua,
In this work, a hibonite-type Ni/La-hexaaluminate (Ni/LHA) synthesized from an industrial
waste is used and compared as catalyst in the dry reforming of methane (DRM) at 973 K.
The structure, catalytic behavior, and ...
Use of response surface methodology to optimize triclosan adsorption on alumina pillared clays in a fixed-bed column for applications in solid-phase extraction
(Elsevier, 2023)
Artículo / Artikulua,
Fixed-bed column studies are generally conducted to consider possible applications in water-purification processes. In this work, three synthetic alumina pillared interlayered clays (Al-PILC) were analyzed in fixed-bed
column ...
Layered double hydroxides for CO2 adsorption at moderate temperatures: synthesis and amelioration strategies
(Elsevier, 2023)
Artículo / Artikulua,
Curving the CO2 atmospheric levels is one of the challenges of this century, given its direct impact on climate
change. Of the several strategies of CO2 capture and storage, sorption-enhanced water–gas shift (SEWGS) ...
Understanding the formation of Al13 and Al30 polycations to the development of microporous materials based on Al13-and Al30-PILC montmorillonites: a review
(Elsevier, 2021)
Artículo / Artikulua,
Hydrolysis of aluminum cations (Al3+), the third most abundant metal in the Earth’s crust, is considered relevant
in many academic fields, including materials science and chemical engineering. AlIII -polycations and ...
Synthesis of zeolite a from metakaolin and its application in the adsorption of cationic dyes
(MDPI, 2018)
info:eu-repo/semantics/article,
The present work reports the synthesis of zeolites from two metakaolins, one derived from the white kaolin and the other derived from the red kaolin, found in a deposit in the city of São Simão (Brazil). The metakaolins ...
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.
