Six specimens of ultrafine RuO2-IrO2-TiO 2 ternary oxide particles with different content ratios have been prepared by a sol-gel method using metal alkoxides. Only a RuO2-rich specimen was composed of a mixture of futile-type oxide phase and a metallic phase, while the other specimens were composed
Sol-gel derived titania based mixed oxides TiO 2 -SiO 2 and TiO 2 -ZrO 2 were used as supports for preparing a series of catalysts with vanadia contents varying between 1-25 wt.%. The supports and the catalysts were characterized by employing 51 V and 1 H solid-state MAS NMR, diffuse reflectance FT-
