摘要
以油菜花粉作为硬模板,采用不同的合成方法诱导碳酸钙(CaCO3)的矿化合成,探讨花粉作为模板对CaCO3晶型和形貌的影响,以及CaCO3晶体的形成机理。同时,以十二烷基苯磺酸钠(SDBS)为软模板诱导合成CaCO3,将其作为对照组实验。分别采用化学沉淀法、水热合成法、气相扩散法制备CaCO3晶体样品,并利用XRD、SEM、FT-IR对样品进行测试和表征。以花粉作为硬模板,可以合成具有特定晶型和形貌的CaCO3。
Pollen used as hard template,mineralization of calcium carbonate is induced with different synthesis method.The effects of pollen on the structure and morphology of calcium carbonate are explored,and the formation mechanism is also discussed.At the same time,SDBS is used as a soft template to induce the synthesis of calcium carbonate as a control group.During the experiment,calcium carbonate crystals are prepared by chemical precipitation method,hydrothermal synthesis method and gas phase diffusion method,and then characterized by XRD,SEM and FT-IR,respectively.The results show that calcium carbonate with specific crystalline form and morphology could be synthesized by using pollen as hard template.
