Global popularization of CuNiO2 and their rGO nanocomposite loveabled to the photocatalytic properties of methylene blue

Abstract

New advancements of photocatalytic activity with higher efficiency, low price are most important, which is challenging in industrialized and many fields. We have introduced CuNiO₂ and CuNiO₂/rGO nanocomposite was generally prepared by the hydrothermal treatment and tested to the photocatalytic studies. Photocatalytic measurements of CuNiO₂ with different weight percentages CuNiO₂/rGO (25/75), (50/50), and (75/25) are achieved to the efficiency under visible light, in this case, CuNiO₂/rGO (50/50) composite have the highest performance is scrutinized. This was obeyed for a synergistic effect between CuNiO₂ nanoparticles and rGO composites. Furthermore, the CuNiO₂, CuNiO₂/rGO (25/75), (50/50), and (75/25) nanocomposite were tested by several analyses like XRD, FT-IR, DRS UV Visible spectroscopy, Raman spectroscopy, and FESEM & HRTEM investigations. In this regard all measurements are very clear and satisfied; therefore we are encouraged for future developing environmental applications.
