Morphology control and mechanisms of CaCO3 crystallization on gas-liquid interfaces of CO2/NH3 bubbles in aqueons-glycine solutions

摘要: As one of the new methods materials preparing, interface-regulated mineralization, has been developed and used to fabricate CaCO3 with mimetic construction natural biogenic structures in present work. Combined effect glycine at different concentrations, novel gas-liquid interfaces CO2/NH3 bubbles have substituted for traditional settled matrix utilized as reaction fields CaCO3. crystals delicate hierarchical morphologies, such scallop-shaped, ellipsoidal spherical structure, obtained special glycine-mediated gasliquid interfaces. The concentration chemical kinetics deeply studied. a result, we successfully captured detail crystallization behaviors stages, which allow us put forward general kinetic model reveal formation mechanism implicate straightforward mean control morphology structure.
