This invention relates to the field of wastewater treatment technology, specifically disclosing a photoanode material, a photoanode, its preparation method, and its application in wastewater treatment. The photoanode material comprises an FeSe2 array layer and a Bi2O2WO4 layer supported on the FeSe2 array layer. FeSe2 has a narrow band gap, good light absorption performance, and photogenerated charge separation capability, which can sensitize other semiconductors with wider band gaps to form heterojunctions, promoting the improvement of photocurrent density and electron quantum yield, and enhancing the photoelectric conversion efficiency of the catalytic material. Bi2O2WO4 is composed of [Bi2O2]. 2+ Layers and [WO4] 2‑ The vertically alternating layers facilitate the separation of photogenerated electrons and holes, thereby enhancing the catalytic oxidation activity of the electrode. The combination of Bi₂O₂WO₄ and FeSe₂ improves their respective solar photoresponse capabilities and photoelectrocatalytic performance, offering significant advantages in environmental engineering.
