ZnO nanoparticles supported on mesoporous MCM-41 and SBA-15: a comparative physicochemical and photocatalytic study
TL;DR: In this article, a simple solvothermal impregnation method was used to prepare ZnO nanoparticles supported on MCM-41 and SBA-15, and the influence of the loading of different supports on the structural characteristics and the photocatalytic activity toward degradation of methylene blue in water under ultraviolet irradiation were investigated.

Synthesis, structural characterization and photocatalytic activity of Ti-MCM-41 mesoporous molecular sieves
Abstract: This paper reports the applicability of hydrothermal synthesis in alkaline medium for preparation of Ti-containing mesoporous MCM-41 materials. The influence of different parameters was investigated, such as the Ti source, the molar ratio between Si and Ti and also the synthesis temperature. Structural analysis shows that the high specific surface area, large pore size and well ordered mesostructure, are partially retained in the titania containing materials. Modifying synthesis temperature, it was shown that MCM-41 isotherms are different for temperatures above or under 140°C. UV-VisDR spectroscopy was used to investigate the local environment of Ti sites. The obtained materials were evaluated for the photocatalytic degradation of Rhodamine 6G in aqueous medium. The best photocatalytic activity was found for the sample prepared at higher ageing temperature of 160°C, at which anatase particles were formed.

Growth of anatase nanoparticles inside the mesopores of SBA-15 for photocatalytic applications
TL;DR: A post-synthesis deposition of titania nanoparticles in the pores of SBA-15 results in highly ordered hexagonal templated materials with anatase plugs for photocatalytic applications.
