In this study, we investigated the electrochemical catalysis potential of hybrid nanocomposites containing CdO, Co and ZnO nanocomposites, as opposed to Zn-O doped have weaker Coulomb interactions due their ionic bonds. Because CdO form a covalent bond, interacts more strongly with O than Zn. order reduce nanoparticle crystallinity, oxygen defects improve interaction between −O in lattice. From SEM micrographs, it appears that does not completely change under influence dopants. It can be seen from image both materials very tightly packed particles. The dopants prevent them absorbing large range visible wavelengths. is energy-dense for 5.28 eV compare 5.14 nanocomposites. fact matrix has tuneable bandgap evident since different types are used its manufacture. There at least three distinct absorption modes around 450, 498, 676 cm−1. addition 450 cm−1 498 vibrational modes, Co-O stretching along [1 0 1] plane also been observed As method studying charge carriers, photoluminescence spectroscopy usually used. This analyze electron-hole pairs (e−/h+) formed by semiconducting blue emission luminescence band 615 nm valence 635 nm. With increasing cobalt zinc concentrations, nanomaterials lose remanent magnetization. demonstrated significant coercive effects pure additively incorporated solutions regardless anisotropic, morphological, porosity, particle size distribution. Electrochemical impedance spectrum measurements were conducted 100 kHz 0.01 Hz. According Nyquist plot, purity Co, show high frequency resistance transfer. Nanocomposites contained & exposed UV light 120 min remove solution. degradation MO virtually nonexistent when no photocatalyst present, but photocatalyst, reach 92.56 %.

Abstract This study investigated the use of functionalized cabuya fibers (FCF) as an effective adsorbent for Hg (II) removal from aqueous solutions. The composition, surface properties, and morphology FCF were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS), Fourier transform infrared spectroscopy (FTIR). effects pH, contact time, temperature, dosage, initial concentration on adsorption process studied. Under optimized experimental conditions, achieved a efficiency exceeding 92%, with maximum capacity 8.29 mg/g. data isotherm analyzed using Langmuir, Freundlich, DR, Temkin models. Notably, Langmuir exhibited highest R² value 0.99, indicating model’s strong applicability. pseudo-second-order kinetic model k 2 = 0.42 mg/g.min was employed to elucidate mechanism. Thermodynamic studies conducted, ΔG° (-6.16 kJ/mol), ΔH° (36.29 ΔS° (141.98 kJ/mol·K) calculated, assessing feasibility process. Additionally, desorption results evaluated, demonstrating that it can be reused up three cycles, achieving rates 74% 62% in third cycle. indicates its stability recycling capacity. Finally, effectiveness demonstrated eliminating approximately 91% real mineral water samples Ecuador. These highlight p promising, eco-friendly, sustainable adsorbents remediation contamination aquatic systems.
