Synthesis and characterization of nano-bentonite by solvothermal method

Nano-particles of bentonite have been prepared by solvothermal method in different conditions. The nano-bentonite was characterized by X-ray fluorescence analysis (XRF), X-ray powder diffraction (XRD), thermal gravimetry analysis (TGA), differential thermal analysis (DTA) and infrared spectroscopy. Scanning electron microscopy (SEM) observations revealed that using of solvothermal method leads to bentonite nanostructure. The reactions were performed in several conditions to find out the role of different factors such as the aging time and temperature on the size and morphology of the nano-structures.

► In this work the nano-particles of bentonite by solvothermal method have successfully been synthesized.
► The process proceeded under different conditions resulting in bentonite nano-particles.
► To our knowledge this method can be used at industrial scale because it does not need special conditions like special surfactants, long times and pressure controlling.
