Preparation of Titanium Containing Mesoporous Materials and Their Performance on Photocatalytic Water Splitting.

摘要

Ti incorporated MCM-48 and MCM-41 photocatalysts were prepared by a rapid and facile procedure. Powder X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen adsorption isotherms, Raman spectrometry and UV-visible diffuse reflectance spectroscopy (DRS) and electron paramagnetic resonance (EPR) were utilized to determine the periodically arranged mesoporous structures and local coordination and geometry of Ti in Ti-MCM-48 and Ti-MCM-41 mesoporous materials. The photocatalytic hydrogen evolution results that carried out under UV light irradiation indicated that with the increase of Ti loading in Ti-MCM-48 and Ti-MCM-41 samples, the photocatalytic activity decreased.
