BiFeO 3 Nanoparticles: The “Holy‐Grail” of Piezo‐Photocatalysts?

Abstract Recently, piezoelectric‐based catalysis has been demonstrated to be an efficient means and promising alternative to sunlight‐driven photocatalysis, where mechanical vibrations trigger redox reactions. Here, 60 nm‐size BiFeO 3 nanoparticles are shown to be very effective for piezo‐degrading Rhodamine B (RhB) model dye with record degradation rate reaching 13 810 L mol −1 min −1 , and even 41 750 L mol −1 min −1 (i.e., 100% RhB degradation within 5 min) when piezocatalysis is synergistically combined with sunlight photocatalysis. These BiFeO 3 piezocatalytic nanoparticles are also demonstrated to be versatile toward several dyes and pharmaceutical pollutants, with over 80% piezo‐decomposition within 120…
