Hydrothermal effect on textural properties of synthesized hydrotalcite of different Mg/Al molar ratio |
초록 |
The synthetic hydrotalcite with Mg/Al molar ratios of 2.0-3.0 were synthesized using magnesium chloride and aluminum chloride precursors by coprecipitation method at low supersaturation conditions followed by hydrothermal treatment under water vapor pressure at 80-180oC. The hydrothermal treatment at increasing temperature from 100-200oC and aging time increased the crystallinity and crystallite size whereas surface area and pore volume decreased with increased in temperature significantly. The synthesized hydrotalcite were characterized by powder X-ray diffraction (XRD) and Field emission scanning electron microscopy (FE-SEM). The specific surface area and average pore volume were obtained using a multiple point nitrogen gas adsorption. |
