General description
CaCO3 occurs naturally as the principal constituent of limestone, marble, and chalk, which can be prepared by the precipitation from dissolved calcium hydroxide and carbon dioxide.
Application
Calcium carbonate can be used as a precursor to prepare Pd/CaCO3, which can be used as a catalyst:
- In Miyaura-Suzuki cross-coupling reactions.
- In the ligand-free Stille cross-coupling reaction between aryl halides and tributylphenyltin to synthesize biphenyls.

Nanocellulose hybrids are promising candidates for biodegradable multifunctional materials. Hybrids of nanocrystalline cellulose (NCC) and amorphous calcium carbonate (ACC) nanoparticles were obtained through a facile chemical approach over a wide range of compositions. Controlling the interactions between NCC and ACC
