开发了 Ni 掺杂 NH2-MIL-125(Ti) 催化剂，用于可见光照射下芳香醇的光催化有氧氧化。结果表明，在可见光照射下，使用O 2 作为氧化剂，在Ni掺杂的NH 2 -MIL-125(Ti)上，不同的芳香醇可以几乎绝对选择性地有效转化为相应的醛。与母体催化剂NH2-MIL-125(Ti)相比，Ni掺杂NH2-MIL-125(Ti)对芳香醇的选择性氧化表现出显着增强的光催化活性。初步研究表明，将Ni纳米颗粒掺杂到NH2-MIL-125(Ti)中可以改善所得催化剂的可见光捕获、电荷分离和电子传输，从而增强光催化活性。目前的工作为有机合成用 MOF 基光催化剂的开发提供了一些指导。 (C) 2016 Elsevier B.V. 保留所有权利。
The Ni-doped NH2-MIL-125(Ti) catalyst was developed for the photocatalytic aerobic oxidation of aromatic alcohols upon visible light irradiation. The results show that different aromatic alcohols can be effectively transformed to their corresponding aldehydes with almost absolute selectivity using 02 as the oxidant over Ni-doped NH2-MIL-125(Ti) upon visible light irradiation. Compared with the parent catalyst NH2-MIL-125(Ti), Ni-doped NH2-MIL-125(Ti) exhibits a significantly enhanced photocatalytic activity for the selective oxidation of aromatic alcohols. Preliminary studies indicate that the doping of Ni nanoparticles into NH2-MIL-125(Ti) could improve the visible-light harvesting, charge-separation, and electron-transport of the resultant catalyst, leading to the enhanced photocatalytic activity. The current work provides some guidance in the development of MOF-based photocatalysts for organic syntheses. (C) 2016 Elsevier B.V. All rights reserved.
