Noble-metal-free LaCoO3/La[Formula: see text]Si5CoO[Formula: see text]/[Formula: see text]-Al2O3 catalysts were developed for complete toluene combustion, and their catalytic activities were investigated. The active oxygen supply from the apatite-type La[Formula: see text]Si5CoO[Formula: see text] promoter successfully improved the oxidation ability of the LaCoO3 activator, and the highest catalytic activity was obtained for the 10 wt.% LaCoO3/20 wt.% La[Formula: see text]Si5CoO[Formula: see text]/[Formula: see text]-Al2O3 catalyst, which oxidized toluene completely at the temperature as low as 300[Formula: see text]C.
