“…Semiconductor materials, like CdS, NiO, TiO2, ZnS and ZnO, have been utilized as photocatalysts [18]. The interfacial properties of the semiconductor bulk could be modified by semiconductor oxides prepared using the impregnation method of supporting oxides with a precursor compound [19]. The doping of the semiconductor metal is generally used to alter and improve the interfacial surface of the substrate material, improving the photocatalytic degradation reaction.…”

This study was conducted to determine the effect of the radiation source and radiation time on the methylene blue (MB) solution by adding Ni-Cd/Al2O3 to the percent degradation of MB. To investigate similar purposes, the pH of the MB solution varied as well. The preparation, characterization, and photocatalytic activity of Ni-Cd/Al2O3 are three steps in this research. The Ni-Cd was prepared by mixing Ni(NO3)2.6H2O and Cd(NO3)2.4H2O. Various concentrations of Ni-Cd were mixed with Al2O3, then heated, stirred, dried, and calcined to form Ni-Cd/Al2O3 powder. The dried powder catalysts were characterized using Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDS), Brunauer-emmett-teller (BET), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Diffused reflectance spectrometer spectra (DR-UV-Vis). Higher degradation was observed at pH 11, when MB was degraded by 68% and 76% using the 5Ni-2Cd/Al2O3 and 6Ni-1Cd/Al2O3 catalysts, respectively. The 6Ni-1Cd/Al2O3 sample has higher absorption, less surface area, and less band gap; therefore, it has higher performance against degraded MB in the solution. In summary, 6Ni-1Cd/Al2O3 is capable of degrading MB and can be utilized in MB dye waste. Copyright © 2023 by Authors, Published by BCREC Group.
