Solid-state chemical reaction-driven BiOIO₃ catalyst for boosting piezocatalytic activation of peroxymonosulfate toward pollutant degradation.

ABSTRACT: A simple and scalable solid-state chemical reaction method was employed to fabricate the BiOIO₃ piezocatalyst. Notably, the BiOIO₃ piezocatalyst, in conjunction with ultrasonic vibration (US) and the peroxymonosulfate (PMS) system, exhibited exceptional catalytic performance in the degradation of pollutants (rhodamine B (RhB) and tetracycline (TC)). The BiOIO₃/PMS/US system achieved an impressive reaction rate constant (RhB dye: 0.4958 min^-1 and TC: 0.1983 min^-1) and high degradation efficiency (RhB dye: 88.8% within 4 min and TC: 86.3% within 10 min) and demonstrated good stability, surpassing the performance of the single BiOIO₃ and other material systems. Radical quenching and EPR spectroscopy experiments further identifi
