METAL OXIDES FROM LIKE-HYDROTALCITES MATERIALS MODIFIED WITH Ga3+ AS CATALYSTS FOR ETHYL BIODIESEL SYNTHESIS
(Soc Brasileira Quimica, 2017-06-01)
The synthesis of like-hydrotalcites materials (layered double hydroxides-LDHs) with molecular formula MgxMy3+(CO3)(OH)(16) 4H(2)O in different ratios Mg2+/M3+ where M3+ is Al3+, Ga3+ or both was carried out by the ...
Potassium-containing hydroxylated hydrotalcite as efficient catalyst for the transesterification of sunflower oil
(Springer, 2018-09)
Different hydrotalcite-based materials were evaluated as heterogeneous catalysts for the transesterification of sunflower oil with methanol. A set of compounds based on magnesia-alumina structures (MgAl hydrotalcites) were ...
Emulsion-mediated synthesis of hierarchical mesoporous-macroporous Al-Mg hydrotalcites
(2017-03-01)
A new sol-gel method mediated by the use of paraffin emulsions is presented for the synthesis of hierarchical mesoporous-macroporous Al-Mg hydrotalcites. Prior to the synthesis, the construction of ternary diagrams for ...
Effect of Different Surface-Charged Lamellar Materials on Swelling Properties of Nanocomposite Hydrogels
(2021-01-01)
This study investigated the effect of different surface-charged lamellar materials on the swelling and diffusion properties of synthesized polyacrylamide-methylcellulose hydrogels (HG). Montmorillonite and thermally ...
Influence of molar fraction of Mg/Al, on the electrochemical behavior of hycrotalcite-epoxy-graphite composites
(Elsevier B.V., 2020-10-01)
The layered structure of hydrotalcite-like compounds is responsible for many chemical and physical properties attractive in designing electrodes for analytical applications. Mg/Al hydrotalcite-like materials were prepared ...
Mixed metal oxides from sucrose and cornstarch templated hydrotalcite-like LDHs as catalysts for ethyl biodiesel synthesis
(2017-01-01)
Sucrose and cornstarch were used as organic templates in the synthesis of hydrotalcite-like layered double hydroxides (LDHs) prepared by the coprecipitation with partial replacement of Mg by Zn, and Al by Fe. Non-template ...
