MCM-41 molecular sieve coupled with lead sulfide quantum dots (PbS-MCM-41) was prepared by ion-exchange method. The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis spectroscopy, infrared spectroscopy (IR) and BET (Brunauer-Emmett-Teller) experiments.
