| 英文摘要 | Albeit that photo-enzymatic catalysis has sparked more and more attention, its efficiency is restricted by lower electron transfer and poor compatibility between the natural enzyme and synthetic photocatalyst. Herein, a metal hydride-embedded titania (MH/TiO2) coating is engineered on graphitic carbon nitride (GCN) to coordinate electron transfer and enzyme protection for photo-enzymatic alcohol production. The MH/TiO2 coating plays two vital roles: (1) protecting alcohol dehydrogenase (ADH) from deactivation by the GCN core and MH in the coating and (2) permitting electron transfer from GCN to nicotinamide adenine dinucleotide (NAD+) and then to formaldehyde catalyzed by ADH. The coordinated photo-enzymatic system could produce methanol at a rate of 1.78 卤 0.21 渭mol min-1 mg(ADH)-1, which is 420% higher than that of the system composed of ADH and GCN without the coating. Moreover, the coordinated system could continuously produce methanol for at least three light-dark cycles, while the system composed of GCN and ADH is completely deactivated after one light-dark cycle. Our study unveils the potential of redox-active mineral coating in coordinating synthetic and biological modules for solar chemical conversion. 漏 |
