Catalysts, Journal Year: 2024, Volume and Issue: 14(1), P. 71 - 71

Published: Jan. 17, 2024

In this study, pure CdO nanoparticles, magnetic Fe3O4 and Fe3O4-CdO nanocomposites were prepared via a solution combustion method using cetyltrimethylammonium bromide (CTAB) as template. These nanomaterial samples characterized by X-ray diffraction (XRD), ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), Fourier-transform infrared (FTIR), Raman spectroscopy, photoelectron microscopy (XPS), transmittance electron (TEM), scanning (SEM) analysis. XRD patterns confirmed the purity crystalline nature of samples. FTIR spectra observed metal-oxygen (M-O) bond formation. UV-vis DRS studies performed to investigate optical properties bandgap energy determination. The surface morphology size Fe3O4, determined TEM SEM Under optimum experimental conditions, applied for photocatalytic activity against Methylene blue dye. visible light irradiation, nanostructures showed an efficient degradation 92% organic dye excellent stability multiple cycles reuse.

Environmental sustainability has gained greater acceptance as an approach to achieving the objective of a secure ecosystem with reliable management system. The best strategy for maintaining healthy is waste management. In this present study, chromium (Cr) adsorption capacity from real tannery wastewater on thermally activated adsorbent, equipped Cucurbita moschata (pumpkin) peel described. adsorbent features were investigated by implementing Fourier transform infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and pHpzc (point zero charges) analysis. Cr was identified EDX SEM images analyzed record surface morphological modifications. 8.7. used treat wastewater, in batch experiment varying parameters including contact time, dose, pH. Under optimal circumstances, 50 mL mixed 2.5 g agitated 10 minutes, allowed settle, then concentration evaluated. level untreated effluent filtrate 3178.6 mg/L, 12.1 respectively. capability removal efficiency 3164.46 mg/g 99.32%, correspondingly, at pH 7.2. biochemical oxygen demand (BOD), chloride (Cl-), chemical (COD) showed decreasing percentage 96.58%, 55.62%, 95.01%. fitting pumpkin follows Pseudo second-order (PSO) kinetic Freundlich isotherm model.
