Palygorskite nanoparticles were prepared by sonochemical reaction. The products were characterized by X-ray fluorescence analysis (XRF), X-ray powder diffraction (XRD), thermal gravimetry analysis (TGA), differential thermal analysis (DTA) and infrared spectroscopy. The morphology and size of the nanorods were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
Acid treated attapulgites catalyze acetylation of alcohols using acetic acid in excellent yield. Natural attapulgites from different states of India: Gujarat, Andra Pradesh and Karnataka were modified by acid activation to prepare solid acid catalysts. Detailed catalyst characterization was carried out by XRD, chemical analysis, SEM, surface area, cation exchange capacity and acidity measurements...
