Hydrothermal Synthesis and Characterization of Cu-Saponite

Abstract:

Hydrothermal synthesis of Cu-saponite was achieved using copper nitrate and sodium silicate as the raw materials. The mixtures of starting materials were treated under hydrothermal conditions at 60–230°C for 6–48h. The effect of different synthetic parameters such as hydrothermal temperature and hydrothermal time on the structure development of Cu-saponite was discussed. All the samples were characterized by X-ray diffraction (XRD), FT-IR, scanning electron microscopy (SEM) and nitrogen physisorption techniques. The results of the study showed that the obtained Cu-saponite exhibited better crystallinity at 200°C for 36h. Both increasing hydrothermal temperature and the duration of hydrothermal treatment yielded better crystallized Cu-saponite as determined by XRD. SEM micrographs revealed plate-like shape of the synthetic Cu-saponite. The results of nitrogen physisorption measurements showed different synthesis conditions resulted in different adsorption-desorption isotherms.
