| 英文摘要 | Calcium dodecyl sulfate (CDS) was used for the first time both as an anionic surfactant and as the source of mineral ions in the precipitation process of calcium carbonate (CaCO3). The simple reaction of the enriched Ca2+ ions at the so-called organic-inorganic interfaces with the slowly bubbled CO2 gas resulted in the metastable vaterite polymorph with various structures. The single-crystalline vaterite of the hexagonal platelets, the lens-shaped structures with hexagonal symmetry, the olive-shaped superstructures and these with a concave at each top of olives, and another metastable polymorph of aragonite were obtained, respectively, depending upon the concentration ratio between CDS and n-pentanol. The synergistic effect of CDS and n-pentanol is believed to play a crucial role in driving the oriented aggregation of metastable nanoparticles. Simultaneously, the novel phase transformation of vaterite to aragonite was observed, implying the possible formation mechanism of aragonite at room temperature and in the absence of magnesium ions. |
