Ultrasonic reduction: an unconventional route to exsolute Ag from perovskite La(Ag)FeO3−δ for enhanced catalytic oxidation activity

Abstract

We explore an uncommon ultrasonic reduction method to exsolute Ag from perovskite La0.87Ag0.03FeO3−δ, forming a composite with enhanced catalytic oxidation activity. Such a mild exsolution is based on the coupling effect of ultrasonic cavitation and reducible BH4−, and holds great potential in the fields of energy and environment catalysis.
