Zusammenfassung:Photocatalytic degradation technology, using solar energy as the driving force, is considered the most possible alternative to remediate environmental pollution. And it is essential to find a stable and efficient photocatalyst. As promising semiconductor‐based photocatalysts, Cu 2 O has acquired massive attention owning to its high conduction band energy, superior visible‐light response‐ability, low cost, eco‐friendly, and abundance. However, the application of origin Cu 2 O faces severe problems due to its photocorrosion and low photoinduced carrier separation. Consequently, it is necessary to improve its photostability and photocatalytic activity by carrying out numerous modification strategies, such as heterostructure construction. Herein, we first summarize the classification and operation principles of Cu 2 O‐based type‐II heterojunction. Then, the application of the Cu 2 O‐based type‐II heterojunction photocatalysts for the removal of tetracyclines, quinolones, and sulfonamides have been discussed. Finally, the pressing issues and perspectives in Cu 2 O‐based type‐II heterojunction photocatalysts application for degrading antibiotics have prospected.
