Hr. Chen et al., Preparation and characterization of manganese oxide confined within ordered porous zirconium oxide channels, MICROP M M, 47(2-3), 2001, pp. 173-178
Manganese oxide nanoparticles were synthesized within ordered porous ZrO2 b
y using wet impregnation technique. The manganese-grafted sample was analyz
ed by XRD, N-2 adsorption, TEM, EDS, EPR, and UV-Vis diffusing reflectance
spectroscopy. The experimental results show that the nanoparticles of manga
nese oxide could be successfully confined and randomly distributed into the
pores of ZrO2. XRD and TEM investigations showed that the ordered porous h
ost structure was still maintained. A significant enhancement of absorption
peaks was detected, which was attributed to the host/guest effect. (C) 200
