Abstract | ||||
In this work, we examined the photocatalytic activity of different composite ratios of doped co-oxide (Co3O4-Ni3O4/Al2O3) with carbon nanotubes (CNTs) toward Celestine blue dye (CBD). This work involves preparation of composite catalyst Co3O4-Ni3O4/Al2O3 doped with CNTs in different percent (2%, 4%, 6% and 8%) by using wet impregnation method. The prepared materials were characterized using Fourier transform infrared spectroscopy (FTIR), Atomic force microscope (AFM) and X-rays Diffraction technique(XRD). The photocatalytic activity of these materials were investigated by following photocatalytic removal of Celestine blue dye at λ max= 542 nm and dye concentration equal to 100 ppm in different irradiation times. The obtained results showed that the best percent of doping the co-catalyst with carbon nanotubes was 6%, which gives a high photocatalytic dye removal equal to 99%. | ||||
