In situ single iron atom doping on Bi₂WO₆ monolayers triggers efficient photo-fenton reaction.

ABSTRACT: Developing an efficient photocatalytic system for hydrogen peroxide (H₂O₂) activation in Fenton-like processes holds significant promise for advancing water purification technologies. However, challenges such as high carrier recombination rates, limited active sites, and suboptimal H₂O₂ activation efficiency impede optimal performance. Here we show that single-iron-atom dispersed Bi₂WO₆ monolayers (SIAD-BWOM), designed through a facile hydrothermal approach, can offer abundant active sites for H₂O₂ activation. The SIAD-BWOM catalyst demonstrates superior photo-Fenton degradation capabilities, particularly for the persistent pesticide dinotefuran (DNF), showcasing its potential in addressing recalcitrant
