“…Kaneva et al reported that the photocatalytic activity of nickel doped on ZnO was better for the degradation of malachite green pollutants than without doping when irradiated using visible light, but increasing the nickel concentration can reduce its performance in degrading malachite green [14]. These results contrast with those reported by Jayswal et al, in which a 10% nickel concentration produced the best photocatalytic activity for the degradation of methyl orange (MO), while at a 3% concentration the performance was worse than that without doping [15]. This finding shows that the presence of doping can change the surface properties of the material which affects the chemical properties of the material and its performance in degrading pollutants.…”

In this research, the adsorption of methylene blue (MB) and methyl orange (MO) on ZnO and nickel-doped ZnO (Ni-ZnO) clusters was investigated through the density functional theory (DFT). The study included the interaction with ionized MB, neutral MB, ionized MO and neutral MO. In the case of Ni-doped ZnO, the two probabilities of nickel multiplicities (1 and 3) have been included in the investigation. The interaction between water and ZnO cluster as well as water with Ni-ZnO multiplicity 1 and multiplicity 3 was also studied. The results showed that nickel doping can decrease the bandgap 25.38% which is promising to shift the UV source to the visible range in the photocatalytic process. For photocatalyst application it will bring the more benefit because it requires the lower energy. Moreover, the nickel doped induce the dye adsorp stronger when the dye attached to dircetly the zinc ion. This guide to design the N-doped ZnO photocatalyst with no nickel atoms on the surface of the photocatalyst.
