摘要

为了提高光催化剂在苯羟基化制苯酚过程中的效率，采用原位复合技术制备了一种新型异质结材料Fe-Co-MOFs/2D-MMT。掺杂钴和蒙脱石载体的改性策略有效地提高了材料的光催化性能。光催化结果表明，该催化剂具有催化苯直接羟基化制苯酚的能力，在最佳反应条件下，产率为30.06 %，选择性为85.73 %。该复合材料在光催化过程中表现出优异的稳定性和效率，为改性MOFs在苯羟基化制酚中的应用提供了新的途径。

Montmorillonite-mediated cobalt-doped Fe-MOF composites: a route to efficient photo-driven benzene hydroxylation

In order to improve the efficiency of photocatalyst in the process of hydroxylation of benzene to phenol, a novel heterojunction material Fe-Co-MOFs/2D-MMT was prepared by in-situ composite technique. The modification strategy of cobalt-doping and montmorillonite-support effectively improves the photocatalytic performance of the material. The photocatalytic results demonstrated that the catalyst displayed the ability to catalyze the direct hydroxylation of benzene to phenol, achieving a yield of 30.06 % and a selectivity of 85.73 % under the optimal reaction conditions. And the composite showed excellent stability and efficiency in the photocatalytic process, which provided a new route for the application of modified MOFs in the hydroxylation of benzene to phenol.

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
