✦ Synopsis

Nanoparticles of Pd supported in the mesopores of titania-modi5ed MCM-41 have been synthesized by the photodeposition method for the 5rst time and characterized by XPS spectroscopy, N 2 sorption isotherms, XRD, TEM, SEM, di4usion re6ectance UV+vis absorption spectra, and Raman spectra. The metallic Pd clusters were dispersed uniformly in the mesopores of titania-modi5ed MCM-41. The photocatalytic activity of Pd-deposited titania-modi5ed MCM-41 has been investigated. For the photoreduction of Cr(VI) to Cr(III), Pd-deposited titania-modi5ed MCM-41 exhibited much higher photocatalytic activity than the supports did.
