| 1 | Metal atom doping-induced S-scheme heterojunction boosts the photoelectric response显示文摘Carrier migration path and driving forces are two crucial factors for charge separation of heterojunction with efficient photoelectric response from the thermodynamic and kinetic perspectives,respectively.Constructing the S-scheme heterojunction and achieving an efficient migration path for space charge separation have aroused great interest,while a thorough insight into tuning interfacial band bending for S-scheme heterojunction is absent.Herein,we report a class of Zn atom-doped CeO_(2)/g-C_(3)N_(4) heterostructure for achieving a new carrier migration path conversion from inferior type-II to advanced S-scheme.Zn-dependent volcano-type plot for Zn-CeO_(2) is established to tune the Fermi level of CeO_(2).The built-in electric field for carrier flow dynamics strengthens when coupling with g-C_(3)N_(4),which significantly boosts the photoelectric response.Based on the intrinsic enzymelike activity of Zn-CeO_(2),we further demonstrate that the Zn-CeO_(2)/g-C_(3)N_(4) S-scheme heterojunction can be explored for constructing a sensitive nanozymatic photoelectrochemical biosensor for the detection of acetylcholinesterase. | Mingwang Liu Jing Wen Ying Qin Jinli Li Yinjun Tang Lei Jiao Yu Wu Qie Fang Lirong Zheng Xiaowen Cui Wenling Gu Chengzhou Zhu Liuyong Hu Shaojun Guo | 2023 | Science China Chemistry2023，66，4： | 0 |
