Abstract

Piezocatalysis is a promising approach for environmental pollutant removal. Monoclinic dibismuth tetraoxide (m-Bi₂O₄) was first applied to piezocatalyze organics under ultrasonic vibration. The built-in electric field with ultrasonic stress drives the separation of holes and electrons in m-Bi₂O₄. Its excellent piezocatalytic activity, reusability and chemical stability make m-Bi₂O₄ a new candidate of piezocatalysis.
