Highly Monodisperse Zirconia-Coated Silica Spheres and Zirconia/Silica Hollow Spheres with Remarkable Textural Properties
Open accessAbstract
High surface area zirconia is an interesting material for many applications. In this contribution, we describe the synthesis of SiO 2 @ZrO 2 and @ZrO 2 (Liz-Marzán, L. M.; Correa-Duarte, M. A.; Pastoriza-Santos, I.; Mulvaney, P.; Ung, T.; Giersig, M.; Kotov, N. A. In Handbook of Surfaces and Interfaces of Materials; Nalwa, H. S., Ed.; Academic Press: San Diego, 2001; Vol. 3) of high surface area zirconia. The synthesis consists of (1) preparing monodisperse silica spheres; (2) coating the spheres with hydrated zirconia; (3) aging the composites; (4) calcining the composite at 1173 K; and (5) leaching the silica with NaOH solution. This process results in the formation of hollow zirconia spheres with a surface area of around 300 m 2 g - 1 . The zirconia is present in the tetragonal polymorph. The final material still contains silicon and sodium. However, it is present in a phase of which the nature could not be fully ascertained.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
