S. Zheng et al., Synthesis, characterization, and photoactivity of nanosized palladium clusters deposited on titania-modified mesoporous MCM-41, J SOL ST CH, 162(1), 2001, pp. 138-141
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.
