Synthesis of high surface area mesoporous carbonates in novel ionic liquid

High surface area mesoporous SrCO3, CaCO3 and MnCO3 with straw-like bundles morphology were synthesized in a novel imidazolium pyruvate ionic liquid. These carbonates were characterized by X-ray diffraction, Fourier transform infrared spectra and transmission electron microscopy. The results revealed that these carbonates have pure orthorhombic and rhombohedral structures, respectively, and the prepared products all show the unique straw-like morphology. Mesoporous properties and high surface areas of SrCO3(118 m2/g), CaCO3(43 m2/g) and MnCO3 (122 m2/g) were also confirmed by the corresponding N2 sorption analyses.
