Zirconia nanoparticles (NPs) with a pure tetragonal phase, stable at high temperatures and with hierarchical pore networks, are synthesized from gelling alginate by complexation of zirconium ions within a fibrous cross-linked biopolymer. The concentration of precursor significantly affected the structural stability, crystal size, and crystal phase of the final material. The zirconia NPs were characterized by thermogravimetric analyses, nitrogen adsorption-desorption, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The method developed herein is straightforward as well as flexible and can pave the way to a host of hierarchical materials for current nanotechnologies.
