Facile Synthesis of Calcium Carbonate Nanoparticles from Cockle Shells

Figure 2

TEM image of cockle shells powders before (a) and after (b) the addition of BS-12. While the micron-sized rough rod-like crystals were observed before adding any catalyst (a), the clear nanosized rod-like crystals were synthesized after adding BS-12 as a catalyst (b).
