New synthesis of a porous Si/TiO2 photocatalyst: Testing its efficiency and stability under visible light irradiation

Abstract

TiO2 nanoparticles were directly coupled with porous silicon and this novel composite material shows very strong photocatalytic activity for the degradation of Rhodamine B with high photochemical stability under visible light irradiation. © 2006 The Royal Society of Chemistry and Owner Societies.
