Synthesis, structural and morphological characteristics of NiO nanoparticles Co-doped with boron and nitrogen

To improve the performance of NiO nanoparticles under source light, a nitrogen and boron co-doped nano powder photocatalyst was collected. The UV-Vis diffusive reflectance spectroscopy (DRS) and photoluminescence (PL) spectroscopy were used to measure photoabsorbance. The morphology of NiO nanophotocatalyst was characterized using Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy equipped with energy dispersive X-ray spectroscopy (SEM-EDS), and X-ray diffraction (XRD). The particle size was in correlation with the calcination temperature. It is found that the average crystallite size and specific surface area of the three co-doped NiO catalysts are near 9.57-10.21 nm, and 132.7-151.9 m2/g, respectively. Degradation of 1-chloro-4-nitrobenzene under UV and visible light illumination was applied to appraise the photocatalytic efficiency. The results indicated that the co-doping of nitrogen and boron performance is a major designation in the band gap decrease, which led to the enhancement of the activity of photocatalytic reaction. The binding energies of O 1s, Ni 2p1/2, Ni 2p3/2, N 1s and B 1s ready a justly complete image of the synthesis sample. The peak of Ni 2p3/2 that emerges at 855.6 eV indicated the detection for NiO. The peak of O 1s at 530.9 eV is ascribed to the O2 − in the NiO. The particles exhibited excellent antimicrobial property.
