Abstract

La presente descripción proporciona materiales catalíticos de perovskita y catalizadores que comprenden metales del grupo de platino y perovskitas. Estos catalizadores se pueden utilizar como materiales de almacenamiento de oxígeno con aplicaciones automotrices, tal como catalizadores de triple vía. También son útiles para reducción de agua o CO2, o almacenamiento de energía termoquímica.
