This article presents a new and facile method for the synthesis of Schiff base compounds with benzimidazole group using low-cost reusable calcium aluminate nanophosphorus catalyst (CaAl2O4). approach avoids harmful solvents reactants, supporting more environmentally friendly process. The maintained its activity heterogeneity over four cycles minimal loss efficiency. process was straightforward eliminated need column chromatography. ligand (HL=(E)-N-((6-(thiophen-2-yl)pyridin-2-yl)methylene)-1H-benzo[d]imidazol-2-amine)) synthesized by reaction 6-(thiophen-2-yl)pyridine-2-carbaldehyde 1H-benzimidazole-2-amine. Subsequently, metal(II) complexes Co(II), Ni(II), Cu(II) were prepared this ligand. Structural analysis both metal carried out various physicochemical spectroscopic methods. Ni(II) Co(II) found to adopt an octahedral geometry, while complex exhibited square-planar structure. Binding studies calf thymus DNA (CT-DNA) at pH 7.2 performed UV-visible spectroscopy, viscosity measurements, thermal denaturation showed that intercalate into produced distinct binding pattern. Molecular docking simulations AutoDock Vina provided insights interaction these B-DNA dodecamer. Furthermore, photonuclease against pUC19 DNA. Agarose gel electrophoresis exhibit photoinduced nuclease activity, confirming their ability cleave upon exposure light.

This study synthesized graphene oxide (GO)/zinc (ZnO)/silver (Ag) composite materials and investigated their photocatalytic degradation performance for ciprofloxacin (CIP) under visible light irradiation. GO/ZnO/Ag composites with different ratios were prepared via an impregnation chemical reduction method characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), photoelectron (XPS). The results demonstrated that optimal conditions (20 mg/L CIP concentration, 15 mg catalyst dosage, GO/ZnO-3%/Ag-doping ratio, pH 5), the exhibited highest activity, achieving a maximum rate of 82.13%. effectively degraded irradiation, showing promising potential water purification applications.
