Infrared Studies of Surface Acidity and Reversible Folding in Palygorskite
Infrared spectroscopy Lewis-acid sites Palygorskite Protonation Pyridine
2012/1/9
The infrared absorption spectra of a palygorskite sample from Cáceres, Spain, showed two previously unreported bands in the OH-stretching region at 3420–3440 and 3220–3230 cm−1 after evacuation ...

The infrared absorption spectra of a palygorskite sample from Cficeres, Spain, showed two previously unreported bands in the OH-stretching region at 3420-3440 and 3220-3230 cm -~ after evacuation at 9...
Fibrous sepiolite crystals derive much of their commercial value from their molecular size channels and grooves. The crystals fold upon drying and these channels and grooves are lost. A model for the ...
