Abstract

In this research, first mesoporous nickel hydroxide nanoparticles were synthesized by solvothermal method. Then the nickel hydroxide nanoparticles were converted into Nickel oxide nanoparticles by maintaining the structure and morphology during heat treatment and then doped with copper (П) by Ball milling method. Since no toxic, expensive, and complex chemicals were used during the synthesis process, the results of this research can be considered scientifically and industrially in the production of other doped nanomaterials. Methods such as scanning electron microscopy (SEM), X-ray diffraction (XRD), energy–dispersive spectroscopy (EDS), and surface area and porosity measurement by nitrogen absorption and desorption method (BET) were used to study the structure and chemical composition of the synthesized nanomaterials. XRD patterns showed FCC structure of the synthesized nanoparticles and the absence of impurity phase. Also, BET measurements showed the mesoporous nature of nanoparticles and good specific surface area and pore volume. The catalytic behavior of copper doped Nickel oxide nanoparticles in the removal and sonophotocatalytic degradation of Phenol pollutant under visible light and ultrasound waves was studied. It was observed that the Phenol substance soluble in water as a model pollutant was destroyed by about 86.5% under visible light and ultrasonic waves after adding copper doped Nickel oxide catalyst.
