Synthesis and Design of MnCO3 Crystals with Different Morphologies by Supported Liquid Membrane

A biomimetic supported liquid membrane (SLM) system was employed to control the morphology of manganese carbonate. Some interesting morphologies including nanowire/hollow spheres/twinborn spheres could be readily generated by using EDA (ethylenediamine), EDTA (ethylenediaminetetracid) or NTA (nitrilotriacetic acid) as cooperative modifiers in the mineralization process, under the conditions of pH 10, 0.01% of crystal modifier and ambient temperature. The key factor in this system was the cooperative template effect of SLM and the crystal modifiers. The clarification of fantastic morphogenesis of them could be valuable for understanding of biomineralization processes.
