Niobate materials have garnered significant interest in recent years due to their potential applications across various fields. As a special property, piezoelectric catalysts based on niobate remain underexplored, primarily chemical inertness and low activity. The development of with stable efficient properties continues pose challenges the fields chemistry science. In this study, novel 30%CuS/0.21%Cs/KNN composite has been successfully synthesized using facile hydrothermal method by depositing CuS nanoparticles external surface 0.21%Cs/KNN cube. By controlling loading amount CuS, catalytic degradation activity title for methyl green MG reached highest point 99.5% under low‐power ultrasound (50 W), which is much higher than that (7.5 times) (5.5 times). addition, atomic force microscopy (AFM) electrochemical tests demonstrated composites good piezocatalytic properties. This work provides meaningful strategy promoting material compounding.
