Ultrasonic reduction: an unconventional route to exsolute Ag from perovskite La(Ag)FeO_3- for enhanced catalytic oxidation activity

We explore an uncommon ultrasonic reduction method to exsolute Ag from perovskite La0.87Ag0.03FeO3-delta, 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.
