Hydrogen peroxide as a crystal growth modifier of CaCO3

Abstract

Using exclusively H2O2 as an additive, facile morphology control over CaCO3 crystal aggregation was realized readily by changing the concentrations of H2O2 and the pH values of the crystallization system. The ionization of H2O2 to [H–O–O] and [O–O]2− and the generated gas molecules played significant roles in modifying the crystal morphologies. Based on the CaCO3 particles morphology through different aging times, a mechanism about the formation of CaCO3 crystals in the presence of H2O2 was proposed.
