Abstract:

Cu3(BTC)2-based (BTC=1, 3, 5-benzenetricarboxylic acid) metal-organic framework film was synthesized on the surface of copper mesh through in situ crystallization at room temperature. In this film, Keggin-type H3PMo12O40 was embedded in partial cavity of Cu3(BTC)2. The film was characterized by X-Ray powder diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectrometer (FT-IR). The surface of copper fiber was evenly covered by the film. It can be estimated that the thickness of film is about 8 μm. In the synthesis process, the role of copper is not only a support, but also a copper source. H2O2 played an important role in synthesis process of membrane, and adding proper H2O2 could accelerate reactive speed effectively. As a heterogeneous catalyst, the catalytic property of the sample was tested through rhodamine B degradation. The film exhibited good catalytic performance in the reaction of rhodamine B degradation. After reaction for 100 min, the degradation degree of rhodamine B reached 98%. The catalyst was reused for three times, and every time it exhibited good catalytic performances during the processes.

Key words: metal-organic framework film, in situ crystallization, copper mesh, polyoxometalate, degradation of Rhodamine B, catalytic oxidation
