摘      要：Developing an efficient photocatalytic system for hydrogen peroxide(H_(2)O_(2))activation in Fenton-like processes holds significant promise for advancing water purification ***,challenges such as high carrier recombination rates,limited active sites,and suboptimal H_(2)O_(2)activation efficiency impede optimal *** we show that single-iron-atom dispersed Bi_(2)WO_(6)monolayers(SIAD-BWOM),designed through a facile hydrothermal approach,can offer abundant active sites for H_(2)O_(2)*** SIAD-BWOM catalyst demonstrates superior photo-Fenton degradation capabilities,particularly for the persistent pesticide dinotefuran(DNF),showcasing its potential in addressing recalcitrant organic *** reveal that the incorporation of iron atoms in place of tungsten within the electron-rich[WO_(4)]^(2-)
layers significantly facilitates electron transfer processes and boosts the Fe(II)/Fe(III)cycle *** experimental investigations and theoretical analyses further elucidate how the atomically dispersed iron induces lattice strain in the Bi_(2)WO_(6)monolayer,thereby modulating the d-band center of iron to improve H_(2)O_(2)adsorption and *** research provides a practical framework for developing advanced photo-Fenton catalysts,which can be used to treat emerging and refractory organic pollutants more effectively.
