Magnetic photocatalysts

 

Magnetic photocatalysts are materials in which the magnetic properties of iron oxide maghemite nanoparticles are combined with the photocatalytic properties of anatase titanium oxide nanoparticles. Essentially, they are nanocomposite particles composed of agglomerates of superparamagnetic nanoparticles coated by a nanocrystalline layer of anatase. Such particles can also be prepared by electrostatically binding maghemite nanoparticles with previously synthesized anatase nanoparticles. Magnetic photocatalysts are intended to be used in the purification of polluted waters. During the purification they are dispersed in water but after the purification process they are magnetically separated
