Lanthanum based high surface area perovskite-type oxide and application in CO and propane combustion
Publikováno v:
Eclética Química, Vol 34, Iss 1, Pp 31-38 (2018)
The perovskite-type oxides using transition metals present a promising potential as catalysts in total oxidation reaction. The present work investigates the effect of synthesis by oxidant co-precipitation on the catalytic activity of perovskite-type
