Abstract

The physicochemical properties (crystal structure, surface acidity, surface area, catalytic activity and electrical conductivity) of TiO2-silica gel mixed oxides have been investigated. A series of mixed oxides of various compositions in the range of 0–100% for each component were prepared by calcining the mixed oxides in air at temperatures of 115, 300, 600 and 1000°C. The results obtained have been discussed and correlated.

Zusammenfassung

Es wurden die physiko-chemischen Eigenschaften (Kristallstruktur, Oberflächenazidität, Oberflächengröße, katalytische Aktivität und elektrische Leitfähigkeit) von TiO2-Kieselgel Mischoxiden untersucht. Eine Reihe dieser Mischoxide verschiedener Zusammensetzung im Bereich 0 bis 100% für jede der Komponenten wurde durch Kalzinieren der Mischoxide in Luft bei Temperaturen von 115, 300, 600 und 1000°C hergestellt. Die erhaltenen Ergebnisse werden diskutiert und miteinander korreliert.
