Abstract
High-quality LDH-NO3-CO3 whiskers were synthesized via a liquid precipitation method using Mg(NO3)2·6H2O and Al(NO3)3·9H2O as raw materials and Na2CO3-NaHCO3 buffer solutions as precipitant. The whiskers were characterized by X-ray diffraction, transmission electron microscope, and Brunauer-Emmett-Teller N2 surface area measurement. The influence of buffer solution concentration on the characteristics of the sample was investigated. The results show that the buffer solution concentration has significant impact on whiskers with intercalated structure. Overall, LDH-NO3-CO3 whiskers with well-defined geometry, distinct intercalated structure, high quality, and good dispersion capability can be obtained under the following conditions: buffer solution volumetric ratio of 60％, reaction temperature of 55 °C, and reaction time of 269 h.
