Spectroscopic characterization of schiff base-copper complexes immobilized in smectite clays
(Sociedade Brasileira de Química, 2010-01-01)
Herein, the immobilization of some Schiff base-copper(II) complexes in smectite clays is described as a strategy for the heterogenization of homogeneous catalysts. The obtained materials were characterized by spectroscopic ...

MINERALOGY AND GENESIS OF SMECTITES IN AN ALKALINE-SALINE ENVIRONMENT OF PANTANAL WETLAND, BRAZIL
(CLAY MINERALS SOC, 2008)
Smectite formation in alkaline-saline environments has been attributed to direct precipitation from solution and/or transformation from precursor minerals, but these mechanisms are not universally agreed upon in the ...
Modification of a Brazilian smectite clay with different quaternary ammonium salts
(Sociedade Brasileira de Química, 2010)
In this work, a smectite clay from the State of Paraiba, Brazil, was treated with six different types of ammonium salts, which is an usual method to enhance the affinity between the clay and polymer for the preparation of ...

A new synthetic smectite-like vanadosilicate containing V3+ in the framework
(2020-03-01)
A new synthetic smectite-like vanadosilicate, named Vanadosilicate Araraquara Madrid (VAM), containing V3+ was prepared by a hydrothermal method and its behavior as catalyst for methanol oxidation was investigated by X-ray ...

Thermal stability of ionene polymers
(2013-06-01)
Two different cationic polymers of the same chemical type and with very similar chemical structures were reacted with a natural bentonite over a wide range of polymer/clay ratios. This study involved the synthesis of ...
