“…It was recorded under parallel direction to the pore axis and it is possible to observe typical MCM-41 morphology in the micrograph. Although it is very difficult to identify ZnS nanoparticles within the pores of MCM-41 materials by using TEM techniques [20], the higher contrast in the image of the ZnS/MCM-41 sample can be associated with the presence of ZnS nanoparticles inside the pores of this sample.…”

The aim of this work is to report the optical and structural properties of ZnS nanoparticles in mesoporous matrix. The samples were obtained by sulfidation of the Zn 2? ion-exchange mesopore in a Na 2 S solution at room temperature. The final product (ZnS/MCM-41) was characterized by X-ray diffraction (XRD) pattern, transmission electron microscopy, scanning electron microscopy (SEM), infrared spectrometry and UV-Vis spectroscopy. Its crystalline structure and morphology was studied by XRD and SEM. Exciton absorption peaks at higher energy than the fundamental absorption edge of bulk ZnS indicates quantum confinement effects in nanoparticles as a consequence of their small size.

“…They were recorded under the direction parallel to the pore axis and it is possible to observe the typical AlMCM-41 morphology in both micrographs. Although it is very difficult to identify CdS NPs within the pores of MCM-41 materials using TEM techniques [34], the higher contrast in the image of the CdSAlMCM-41 sample can be associated with the presence of CdS nanocrystals inside the pores of this sample.…”

“…Semiconductor heterojunctions such as CdS/TiO 2 , CdS/ZnO, CdS/ZnS, and CdS/C 3 N 4 have been widely reported in photocatalysis due to the promoted separation of photo-generated charges at the interface [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]. In addition, microporous and mesoporous silica could be used as support for dispersing CdS quantum dots [57][58][59][60][61][62][63][64][65][66][67][68]. A c c e p t e d M a n u s c r i p t…”
