摘要：Abstract: Carrier separation efficiency influences the final reactive oxygen species product of the cascade reaction, and constructing a heterojunction interface is an ideal strategy to improve it. Herein, we engineered a self-sufficient photo-Fenton system using a CuxO/CuS/ZnlnS4 heterojunction, which enabled the directional generation of sufficient singlet oxygen ('0z)via a hole-dominated cascade reaction, achieving efficient degradation of amoxicillin, The CuS interface between CuO and ZnlnzS.originated from the in-situ transformation of CuO, and the stepwise presence ofdifferent components during the XRD, XPS, and TEM structure characterizationconfrmed it. This heterojunction interface induced a band structure from the initial type l to S-scheme, optimizing carrier separation efficiency and transfer pathway, which matched with hole-dominated cascade reactions. Consequently, HO2 was in situ produced via water oxidation reaction and eventually converted into 'O2 by highly active holes. In addition, the CuS interface prevented amoxicillin in the aqueous system from directly reacting with holes while ensuring that HO molecules adequately participated in the cascade reaction. In summary, the tailored heterojunction interface boosted carrier separation efficiency, driving the completion of the hole-dominated cascade reaction. This process facilitated the directional generation of abundant 'O, for the efficient degradation of contaminants.
