Abstract
In this reported article, a highly efficient, stable and low cost CuO/TiO2@MOF-5 composite has been synthesized by in-situ incorporation of pre-synthesized precursors into MOF-5. The formation of synthesized samples has been confirmed by Powder X-ray diffraction (PXRD), Scanning electron microscopy (SEM) images, Energy dispersive X-ray (EDX) images and Ultraviolet visible spectrophotometry. The synthesized samples are found efficient for photoelectrochemical oxygen evolution reaction (OER) and photodegradation of organic dyes (methylene blue/methyl orange). It has been observed that CuO/TiO2@MOF-5 shows lowest onset potential, highest current density and better OER activity as compared to some of previously reported Cu-based working electrodes. It required only 263 mV overpotential to deliver the benchmark 10 mA cm−2 current density. In the same way, CuO/TiO2@MOF-5/NF exhibits maximum ability to degrade methylene blue and methyl orange as compared to all other samples.
