“…The influence of the partial substitution of cations with different oxidation states within the (AA 0 BB 0 O 3±d ) perovskite network [5,7,15,[18][19][20][21][22][23] and the use of different supports to increase the overall surface area of the catalyst have been the main approaches achieved in previous studies [6,24]. In a prior study [15], our group has determined how the partial substitution of Ni by Co in the lanthanum perovskite strongly affects the oxidation capability of the samples.…”

The total oxidation of toluene is studied over catalytic systems based on perovskite with general formula AA 0 CoO 3-d (A = La, A 0 = Sr). The systematic and progressive substitution of La 3? by Sr 2? cations in the series (La 1-x Sr x CoO 3-d system) of the perovskites have been studied to determine their influence in the final properties of these mixed oxides and their corresponding reactivity performance for the total oxidation of toluene as a model volatile organic compound with detrimental effects for health and environment. The structure and morphology of the samples before and after reaction have been characterized by XRD, BET and FE-SEM techniques. Additional experiments of temperature programmed desorption of O 2 in vacuum and reduction in H 2 were also performed to identify the main surface oxygen species and the reducibility of the different perovskites. It is remarkable that the La 1-x Sr x CoO 3-d series presents better catalytic performance for the oxidation of toluene, with lower values for the T 50 (temperature of 50 % toluene conversion) than the previously studied LaNi 1-y Co y O 3 series.

“…The redox properties of the B-position ions, the nature and concentration of O 2 adspecies, and the existence of lattice defects are usually believed to be responsible for the high catalytic performance of perovskite-type oxide [49]. Agarwal et al [50] investigated the catalytic oxidation of toluene over LaMO 3 (M = Co, Fe, and Cr) synthesized via a decomposition method. They found catalytic performance as follows: LaCoO 3 > LaFeO 3 > LaCrO 3 .…”
