Photocatalyst/single-atom catalysts core–shell heterojunctions were constructed. The strong built-in electric field across the heterojunction promotes charge separation and migration. Photogenerated electrons could rapidly (2 ps) transfer from the ZnO “core” to the single-atom Co catalysts “shell”, boosting the catalytic performance for heterogeneous photo-Fenton-like reaction.

富氧空位 ZnO@单原子钴核壳结中的定向和超快电荷转移用于类 Fenton 反应

构建了光催化剂/单原子催化剂核壳异质结。异质结上强大的内置电场促进电荷分离和迁移。光生电子可以快速（2 ps）从ZnO“核”转移到单原子Co催化剂“壳”，从而提高非均相光芬顿反应的催化性能。
