Catalytic Dye Oxidation over CeO2 Nanoparticles Supported on Regenerated Cellulose Membrane

A novel regenerated cellulose (RC) membrane containing cerium oxide (CeO2) nanoparticles is described in detail. In this work, CeO2 with high surface area and mesoporosity were prepared by a modified template-assisted precipitation method. Successful synthesis was achieved using nitrate as precursor, adjusting the final pH solution to around 11 ammonium hydroxide ethylene diamine, annealing at 550 °C for 3 hours under protective gas flow. This resulted of 55.55 m².g–1 nanoparticles. The particles synthesized environmentally friendly catalyst cellulose/CeO2 characterized Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Electron paramagnetic resonance (EPR), Brunauer-Emmett-Teller (BET) measurements. g-value 2.276 has confirmed presence superoxide species EPR. photocatalytic activity evaluated through degradation methylene blue visible light irradiation UV-VIS degraded 80% 120 minutes, showing better than catalyst, which approximately 62% same period. It been proven that RC not only good transparent supporting material but also adsorption high-performance catalyst.
