BFO with smallest thickness exhibits excellent catalytic activity with SO4·- and ·OH as major reactive species for degrading organic pollutants
Decreased thickness exposes more Fe2+ sites and improves piezoelectric effect to accelerate Fe2+ regeneration, enabling enhanced synergy between PDS activation and piezocatalysis
