The Sea Urchin-shaped CaCO3 via Template Mineralization on Surface-functionalized Vaterite Particles by Tiopronin-protected Gold Nanoparticles
The sea urchin-shaped particles of CaCO 3 , i.e., spherical vaterite covered with needle-shaped aragonite, were formed by template mineralization of CaCO 3 in the presence of the anionic gold nanoparticles modified spherical vaterite in water.
