Preparation of Ceria Fibers Via Electrospinning Process
MetadataShow full item record
Electrospinning is an interesting technique with various potential applications. CeO2 fibers production was achieved via this technique. In this work, the prepared condition and the fiber morphology were investigated and described. The optimum condition was 15 kV, 7 cm in distance between needle tip and ground collector, 50 wt% of i-propanol in the co-solvent. The obtained fibers were continuous with a diameter of 900 nm. The smooth electrospun fibers produced were dried for one hour, and then calcined at 450 OC for 3 hours. The calcined fibers were reduced to 600 nm and cracked on the fibers. They were ceria fibers, what verified by EDX, and XRD pattern. They had high specific surface area to volume ratio, and monolith fibers, which is applied for catalytic applications.
