Photocatalytic Remediation of Methylene Blue and Antibacterial Activity Study Using Schiff Base - Cu Complexes

Abstract Photocatalytic degradation of organic dyes under visible light and ultraviolet radiation is an efficient strategy for effluent treatment. This work describes the design of novel Cu(II) complexes using the ligand N'-(3-hydroxy-4-methoxybenzylidene)nicotinohydrazide and their application in the photocatalytic degradation of the organic dye, methylene blue (MB). The photocatalytic degradation of MB follows pseudo first-order kinetics with high correlation coefficient values (R2> 0.95), making them useful as simple and low-cost organic dye degradation agents. The antibacterial screening studies of the ligand and the Cu(II) complexes by disc diffusion method show the systems to exhibit activity against Escherichia coli (gram negative) and Bacillus circulans (gram positive).

Abstract In this study, a combustion method as an efficient, easy, low-cost, and eco-friendly technique was used to synthesize nano-ZnO as a matrix with different yttrium doping ratios with different doping concentrations. Not only X-ray diffraction (XRD), but also scanning electron microscopy (SEM), and Fourier transformation Infrared spectroscopy (FT-IR) technique employed to characterize the structural and surface morphology of the Y2O3-ZnO nanocomposites. The obtained results supported ZnO's growth from crystalline to satisfactory nanoparticle structure by changing the yttrium doping concentrations inside ZnO nanoparticles. Moreover, UV-Vis diffuse reflectance spectroscopy, AC electrical conductivity, and current-voltage characteristics were considered to characterize the effects of yttrium doping on the energy bandgaps and electrical/dielectric properties and discussed the parameters of the ceramic varistors of the studied Y2O3-ZnO nano-complex oxides. The photocatalytic degradation efficiency of phenol, Methylene Blue, and Rhodamine B was investigated using all prepared Y2O3-ZnO nanostructured samples. As the yttrium doping ratios increased, the photocatalytic efficiency increased. After the addition of moderate Y3+ ions-doping, Further generation of hydroxyl radicals over ZnO. For Y2O3-ZnO (S5), the optimal photocatalyst is a degradation of 100 % of phenol, Methylene Blue, and Rhodamine B solutions compared to 80% of photocatalysis for ZnO stand alone. The prepared Y2O3-ZnO nanostructured materials are considered novel potential candidates in broad nano-applications ranging from biomedical and photocatalytic degradation for organic dyes and phenol to environmental and varistor applications.

Semiconductor Photocatalyst

Amorphous semiconductor photocatalysts are highly desirable because they are facile and low-cost to prepare in comparison with the crystalline ones. The amorphous semiconductor with photocatalytic activity has been rarely reported. In this work, a new amorphous semiconductor photocatalyst, Co4I3O[Formula: see text]H[Formula: see text][Formula: see text][Formula: see text][Formula: see text]3H2O, was successfully developed. Its microstructure is composed of irregular particles with size of 2–20[Formula: see text][Formula: see text]m. In photocatalytic degradation of rhodamine B (RhB), or methylene blue (MB) dyes driven by visible light, the Co4I3O[Formula: see text]H[Formula: see text][Formula: see text][Formula: see text][Formula: see text]3H2O sample exhibited pronounced activity. Its activity is higher than Degussa P25 (commercial TiO[Formula: see text] in RhB degradation. It was testified that the degradation of RhB is due to the intrinsical photocatalytic role of Co4I3O[Formula: see text]H[Formula: see text][Formula: see text][Formula: see text][Formula: see text]3H2O. The reusability of the Co4I3O[Formula: see text]H[Formula: see text][Formula: see text][Formula: see text][Formula: see text]3H2O photocatalyst was also investigated.
