The role of surface hydrolysis of ferricyanide anions in crystal growth of snowflake-shaped α-Fe2O3†
Abstract
Selective adsorption and surface hydrolysis of [Fe(CN)6]3− anions on α-Fe2O3 crystals was found to be a crucial process in the formation of a snowflake-like morphology, and the established mechanism is complementary to the classical theories of crystal growth.
