Abstract A detailed review was made on the dissociation mechanism of Iron(III) (hydr)oxides such as non-reduction dissociation, reduction dissociation and catalyzed dissociation of electron transfer. The ultrafine hematite particles were prepared to be successful from catalyzed dissociation mechanism of interfacial electron transfer. The mechanism can be applied to many fields such as nanomaterials, geoscience, metal corrosion, soil chemistry, environmental science, and so on.
Key words Iron oxide, Electron transfer, Catalyzed dissociation, Preparation
