Abstract
Nanoparticles of Pd supported in the mesopores of titania-modified MCM-41 h ave been synthesized by the photodeposition method for the first time and c haracterized by XPS spectroscopy, N-2 sorption isotherms, XRD, TEM, SEM, di ffusion reflectance UV-vis absorption spectra, and Raman spectra. The metal lic Pd clusters were dispersed uniformly in the mesopores of titania-modifi ed MCM-41. The photocatalytic activity of Pd-deposited titania-modified MCM -41 has been investigated. For the photoreduction of Cr(VI) to Cr(III), tit ania-modified MCM-41 exhibited much higher photocatalytic activity than the supports did. (C) 2001 Academic Press.
