CdIn2S4 Modified Uio-66 Metal Organic Framework Photocatalyst for Environmental Application and Production of Renewable Energy Sources

Abstract

The UiO-66(Zr) metal-organic framework has been synthesized by a modified solvothermal method. The UiO-66(Zr) nanoparticles were subsequently deposited on the surface of the CdIn2S4 microflower to prepare the binary composites. The CdIn2S4 modified UiO-66(Zr) materials have been characterized by using several analytical techniques like XRD, UV-Vis DRS, FESEM, HRTEM, PL and FTIR. The XRD results confirm the formation of highly crystalline phase of pure Cubic CdIn2S4. The XRD profile of CdIn2S4/UiO-66(Zr) material contains diffraction peaks for CdIn2S4 phase along with the characteristic diffraction peaks for UiO-66(Zr). The CdIn2S4/UiO-66(Zr) material exhibited enhanced visible light absorption property in comparison to the parent UiO-66(Zr) species. The band position of the CdIn2S4 and UiO-66(Zr) components are so aligned that photoelectron migration from conduction band (CB) of CdIn2S4 to CB of UiO-66(Zr) is facilitated leading to enhanced charge carrier separation in the composite material. The CdIn2S4/UiO-66(Zr) materials have been evaluated as an excellent visible light active photocatalyst for mineralization (92 %) of triclosan pesticides and generation of renewable H2 energy (2.95 mmolg-1h-1). The detailed study of the characterization....
