We prepared antimony metal films via electrodeposition, followed by the synthesis of Sb2S3 through a chemical vapor phase reaction. Finally, an Sb2O3 film was deposited onto using bath method, successfully constructing heterojunction photocathode Sb2S3/Sb2O3; synthesized Sb2S3/Sb2O3 is classified as Type I heterostructure. The resulting exhibited photocurrent density −0.056 mA cm−2 at −0.15 V (vs. RHE), which 1.40 times higher than that alone under simulated solar illumination. Additionally, demonstrated lower carrier recombination rate and faster charge transfer compared to Sb2S3, evidenced photoluminescence electrochemical impedance spectroscopy tests. For these reasons, obtained hydrogen precipitation 0.163mL h−1, twice condition 60 min light exposure. significant enhancement in photoelectrochemical performance attributed formation heterojunction, improves both separation efficiency. This strategy holds promising potential for visible light-driven water splitting.
