Abstract

We explore an uncommon ultrasonic reduction method to exsolute Ag from perovskite La_0.87Ag_0.03FeO_3−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.
