Controlled synthesis of calcium carbonate crystals with superstructure on the templates of bamboo leaves/Mg2+
In this paper,a kind leaf of fresh plant — bamboo,was used as template to control the growth of calcium carbonate at room temperature.The products were characterized by SEM,XRD and FTIR.The nucleation and growth of aragonite crystals were induced by making use of the bamboo leaves containing a lot of biomacromolecules in the presence of Mg2+.Different morphologies and structures of the products were obtained by adjusting the concentration ratio of Mg2+ to Ca2+.The results show that crystal morphologies of CaCO3 produced on the bamboo leaves and glass in the presence of Mg2+ were changed.The products with self-assembly and self-similarity superstructures were gained in bamboo leaves/Mg2+ system.This study may supply a new method for the synthesis of inorganic materials with superstructures.
