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

Abstract

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.
