A comparative study of acid and alkaline aluminum extraction valorization procedure for aluminum saline slags
(Elsevier, 2022)
Artículo / Artikulua,
A management process for saline slags, one of the wastes from Secondary Aluminum Production, is proposed. The process begins with a grinding step, followed by washing with water, which removed the fluxing salts but provoking ...
Effect of the synthesis method on the morphology, textural properties and catalytic performance of La-hexaaluminates in the dry reforming of methane
(Elsevier, 2021)
info:eu-repo/semantics/article,
This work describes the synthesis of nickel/lanthanum hexaaluminates (NiO/LHA), optimizing the LHA synthesis method, as well as their performance in terms of stability and catalytic activity in the dry reforming of methane ...
Catalytic valorization of CO2 by hydrogenation: current status and future trends
(Taylor and Francis, 2021)
info:eu-repo/semantics/article,
Terrestrial environmental and biological systems are being threatened by the tremendous amount of human carbon dioxide emissions. Therefore, it is crucial to develop a sustainable energy system based on CO2 as chemical ...
Titania-triethanolamine-kaolinite nanocomposites as adsorbents and photocatalysts of herbicides
(Elsevier, 2021)
info:eu-repo/semantics/article,
Kaolinite-titania adsorbents/photocatalysts were prepared by functionalizing a kaolinite with titanium(IV) triethanolaminate isopropoxide by the sol–gel route. These materials were characterized by various techniques and ...
Experimental and theoretical studies of the interaction of ketoprofen in halloysite nanotubes
(Elsevier, 2021)
info:eu-repo/semantics/article,
In recent years, the application of halloysite (HAL) in the conception of drug systems has become important due to its excellent physicochemical properties. Ketoprofen (KET) is widely used around the world as an anti-inflammatory ...
Improved photocatalytic and antibacterial performance of Cr doped TiO2 nanoparticles
(Elsevier, 2021)
info:eu-repo/semantics/article,
The effect of Cr and N doping in the adsorption capacity, photocatalytic properties and antibacterial response of TiO2 anatase nanoparticles is analyzed. The nanoparticles (N-TiO2, Cr-TiO2 and Cr/N-TiO2) were prepared by ...
Synthesis strategies of alumina from aluminum saline slags
(Elsevier, 2023)
Artículo / Artikulua,
Aluminum saline slags is a waste of the metallurgical industry that presents serious environmental problems
since it needs very extensive areas for its disposal, the toxicity it causes in the atmosphere and groundwater, ...
Metal-Al layered double hydroxides synthesized from aluminum slags as efficient CO2 adsorbents at pre- and post-combustion temperature
(Elsevier, 2023)
Artículo / Artikulua,
Layered double hydroxides (LDH) have been proposed as the materials that offer the best performance in the moderate-temperature range, between 200 and 450 °C, for CO2 adsorption, so the effect of some synthesis parameters ...
Classical and new insights into the methodology for characterizing adsorbents and metal catalysts by chemical adsorption
(Elsevier, 2023)
Artículo / Artikulua,
The adsorption phenomenon has been used extensively to achieve and explain solid-state reactions, control contamination, and purify liquids and gases. This process implies the use of a porous medium or a material with ...
Catalytic photodegradation of organic compounds using TiO2/pillared clays synthesized using a nonconventional aluminum source
(Elsevier, 2022)
Artículo / Artikulua,
This study evaluates the photocatalytic degradation of 2,6-dichlorophenol (2,6-DCP), triclosan (TCS) and bisphenol A (BPA) by ultraviolet (UV) and visible (VIS) light in the presence of TiO2/catalysts synthesized by wet ...
