Synthesis and Photoluminescence of Mesoporous CeO2 Nanofibers Using Porous Anodic Alumina as Template
Abstract:
Using porous anodic aluminium oxide(AAO) membrane as template,a precursor containing triblock copolymer EO20PO70EO20(P123) as porogen,Ce(NO3)3·6H2O as the cerium source and ethanol as the solvent was loaded into the AAO nano-channels by a pressure-induced technique under vacuum.After heat treatment at 600℃ for 180 min and removal of AAO by NaOH,one-dimensional CeO2 nanofibers with mesoporous structure were fabricated.The obtained samples were characterized by means of SEM,TEM,XRD,EDS and N2 sorption and desorption.The results show that the CeO2 nanofibers have mesopore structure and high surface area,and good photoluminescence property.
