Description
Summary:The doping of cerium (Ce) into hydroxyapatite (HA) crystals has been shown to impart antibacterial properties. In this study, ultralong flexible Ce-substituted HA (Ce–HA) nanofibers decorated by CePO 4 nanoparticles are synthesized using a solvothermal method. The obtained products predominantly consist of nanofibers, while the number of CePO 4 nanoparticles attached to the nanofiber surfaces gradually increase and partially agglomerate as the Ce molar fraction (0–8 at%) increases. The Ce ions are doped into the HA lattice in mixed valences of Ce 3+ and Ce 4+ , which significantly increases grain size and crystallinity of Ce–HA nanofibers. Furthermore, the effect of Ce 3+ doping on formation mechanism of the samples is discussed.
