Effect of LaCoO3 perovskite deposition on ceria-based supports on total oxidation of VOC

Abatement of toluene from polluted air over Mn/Clinoptilolite–CeO2 nanopowder: Impregnation vs. ultrasound assisted synthesis with various Mn-loading

“…Furthermore, catalytic oxidation is more efficient in low concentration of contaminants [11,17,18]. The catalysts used for the abatement of VOCs are divided into three groups; precious metals, transition metals and perovskite type materials [19][20][21][22][23]. In spite of high catalytic activity of noble metals, they are expensive and can be easily deactivated by sintering or poisoning.…”

Catalytic Removal of Toluene over Co3O4–CeO2 Mixed Oxide Catalysts: Comparison with Pt/Al2O3

“…Among them, perovskites, manganese and cobalt oxides have received considerable attention for catalytic oxidation of VOCs [1][2][3][4][5][6]. The presence of ceria-based oxides as supports for perovskites can further improve the specific activity, increasing the dispersion of the perovskite phase and enhancing the oxygen mobility [7,8]. The high VOCs oxidation activity of Co 3 O 4 on Y 2 O 3 doped ZrO 2 , prepared in presence of ethylenediamine, was ascribed to the improved dispersion of cobalt oxide along with to the reducibility of cobalt species, at low-temperature, promoted by yttrium [5,6].…”

Effect of the calcium on the textural, structural and catalytic properties of La1–x Ca x Co1–y Fe y O3 perovskites

“…Within this type of structure, the LaCoO 3 perovskite is one of the most studied phases as catalyst in oxidation reactions [1][2][3][4][5], especially those concerning pollution abatement [4][5][6]. Moreover, a wide range of cations has been used to substitute both the A-site and B-site (La and Co, respectively) to modify the valence of B cation, redox properties, crystalline structure and non-stoichiometry, and to control the oxygen vacancies and oxygen storage capacity.…”
