Exsolved metal-boosted active perovskite oxide catalyst for stable water gas shift reaction

We designed a Ni-exsolved perovskite catalyst for the high-temperature water–gas shift reaction. The perovskite particle has the formula of La0.9Fe0.95Ni0.05O3 and has metal nanoparticles (NPs) exsolved on its surface after reduction treatment. XRD, SEM, HR-TEM and XPS analyses were used to confirm the existence of the exsolved Ni metal NPs. This catalyst provided higher CO conversion and H2 yield, and exceptionally better catalytic stability...
