Abstract The discharge of dye residues from the textile industry is a major contributor to water pollution, highlighting urgent need for effective wastewater treatment solutions. This study investigates synthesis ZnO and Bi₂O₃ nanoparticles using ionic liquid-assisted methods enhanced photocatalytic degradation methylene blue. Three liquids were employed: 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]-BF₄), hexafluorophosphate ([BMIM]-PF₆), chloride ([BMIM]-Cl). synthesized...
Three different metal oxides based on Mn2O3 with TiO2 or NiO were synthesised. Pt PtNi nanoparticles anchored each support, creating a set of nine samples that tested for the oxygen reduction reaction (ORR) and evolution (OER). PtNi/Mn2O3-NiO showed most promising results ORR as evidenced by lowest Tafel slope, highest diffusion-limited current density number electrons exchanged, along stability. The best performance reflects its electrochemical surface area charge-transfer resistance....
Dye residues from the textile industry significantly contribute to water pollution, necessitating effective wastewater treatment methods. This study reports successful synthesis of zinc oxide (ZnO) nanoparticles using various ionic liquids (ILs), [BMIM]-BF4, [BMIM]-PF6, and [BMIM]-Cl, as mediators. The synthesized nanomaterials were characterized techniques, including X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM),...
In this work, TiO2 nanopowder (TIP600) was prepared by a sol–gel method and titanium isopropoxide, glacial acetic acid, deionized water were used as the starting materials. Adsorption of congo red (CR) on Degussa-P25 (P25), commercial (C-TiO2), TIP600 investigated. But, photochemical photocatalytic event not for adsorption process. CR onto adsorbents studied at different temperatures (25.0, 40.0, 50.0°C) various adsorbent doses (0.1, 0.05, 0.025 g). The kinetics dye has been investigated in...
Abstract The thermal oxidative degradation kinetics of poly(ethylene terephthalate) (PET) copolymers modified with poly(lactic acid) (PLA) were investigated thermogravimetric analyzer (TGA). properties the products also determined by differential scanning calorimeter (DSC) technique. Waste PET (P100) obtained from postconsumer water bottles was a low‐molecular‐weight PLA. PET/PLA weight ratio 90/10 (P90) and 50/50 (P50) in samples. samples compared those (P100). segmented block and/or random...
Developing bifunctional oxygen electrode materials with superior activity for reduction (ORR) and evolution (OER) reactions is essential advancing regenerative fuel cell rechargeable metal–air battery technologies. This present work deals the synthesis characterization of electrocatalysts containing Pt Ni nanoparticles supported on nitrogen-doped mixed metal oxides (Mn2O3-NiO) systematic evaluation their ORR/OER performance in an alkaline medium. These have been successfully synthesized by a...
