Results and discussion
- Photocatalytic activity equation / description:
Whereas iron (hydr)oxides have an absorption band between 1.9 and 2.1 eV, the high resistance of the substances subdues photoactivity.
Applicant's summary and conclusion
- Conclusions:
- No known photocatalytic activities of iron oxide and ferrite pigments.
