Cerium oxide nanoparticles (ceria NPs) attract a great research and commercial interests due to its observable capability to capture radicals and dissolved oxygen molecules. Keeping ceria NPs in active form; containing Ce+3 ions with O-vacancies, is a big challenge to be fitted into wide variety of applications such as free radical scavengers in bio-medicine, bacteria filters in water waste treatment, and oxygen sensing in environmental monitoring. This novel work presents active ceria NPs on nanofibers host. It is suggested to decorate the surface of electrospun nanofibers of PVA and PEO, as host media, with the active ceria NPs. To achieve this aim, PVA and PEO nanofibers containing active ceria NPs were electrospun by a conventional needle electrospinning and Nanospider machine for producing commercial scale nanofibers. SEM image shows that the ceria NPs are successfully located at the surface of nanofibers. Optical characterizations, absorbance spectroscopy and band gap measurements, show that there is reasonable activity of ceria NPs after electrospinning. Therefore, it is concluded that there is a possibility to host active ceria NPs over the electrospun nanofibers which can be helpful for different applications in green chemistry and Materials.
