被撤回的出版物: TiO2/Cu-MOF/PPy composite as a novel photocatalyst for decomposition of organic dyes (Retracted article. See vol. 34, 2023)

Herein, we report the novel metal organic frameworks (MOFs)-based polypyrrole (TiO2/Cu-MOF/PPy) composite via facile hydrothermal technique. The prepared composites are characterized by X-ray diffractometer; microstructural characterization is done with field emission scanning electron microscopy (FESEM); and Fourier-transform infrared spectroscopy, X-ray photo-electron spectroscopy, UV-Vis absorbance spectra, and UV-Vis diffuse reflectance spectra analysis are obtained. The catalytic behavior is examined through the decomposition of methylene blue, rhodamine B, and methyl orange, as a standard dyes under visible light irradiation. Enhanced photocatalytic activities for the novel TiO2/Cu-MOF/PPy composite under visible light are attributed to the high charge separation, absorption, and carrier mobility of MOFs-based polypyrrole composite. Our result shows a great potential of MOFs-based polymer materials as catalyst under visible light radiation for the decomposition of industrial organic dyes.

Automated summary

The novel metal organic frameworks (MOFs)-based polypyrrole (TiO2/Cu-MOF/PPy) composite was prepared via a facile hydrothermal technique. Characterization of the composites showed enhanced photocatalytic activities under visible light, attributed to high charge separation, absorption, and carrier mobility properties of the MOFs-based polypyrrole composite.
