- Abstract
A noble metal-free apatite-type La10Si5CoO27−δcatalyst with high thermal durability for toluene combustion has been prepared via coprecipitation followed by calcination at 1000 °C. It completely oxidized toluene at 310 °C, which was comparable to that of 0.1 wt % Pt/Al2O3calcined at 1000 °C (290 °C). Furthermore, La10Si5CoO27−δexhibited high catalytic activity even after calcination at 1400 °C via a solid-state reaction route, and the complete oxidation of toluene was realized at 330 °C, lower than that of 0.1 wt % Pt/Al2O3calcined at 1400 °C (380 °C).An apatite-type La10Si5CoO27−δcatalyst with high thermal durability was prepared.

For La10Si5CoO27−δcalcined at 1400 °C, complete toluene combustion was realized at 330 °C, lower than that of Pt/Al2O3calcined at 1400 °C (380 °C).
