Abstract
The hematite α-Fe2O3 is considered as low cost-effective semiconductor for photo-catalysis recently. We have prepared high quality α-Fe2O3 nanopowder by sol-gel method, as shown by XRD diffraction, we could find that the powder are as small as 5-10nm. We also characterize the photo-catalysis properties on such magnets, which show unique photo-induced catalysis capacity.
