Immobilization of semiconductor nanoparticles formed in reverse micelles into polyurea via in situ polymerization of diisocyanates

Nanoparticles of CdS, ZnS, TiO2 or AgI, formed in reverse micelles, have been immobilized into polyurea via in situ polymerization of hexamethylene diisocyanate; the CdS– or ZnS–polyurea composites obtained were utilized as photocatalysts.
