Amphiphilic Templating of Mesostructured Zirconium Oxide
Abstract
The synthesis of zirconium oxide with a mesostructured framework (Zr-TMS) has been achieved through the use of amphiphilic compounds with a variety of headgroups (anionic and nonionic) and tail group chain lengths (1−18 carbons). Anionic surfactants with phosphate, carboxylate, sulfate, and sulfonate headgroups led to disordered hexagonal and/or layered phases. Mesoporous zirconia with high surface areas could be obtained through calcination of materials templated with phosphate amphiphiles; the phosphate headgroups remained on the pore walls and appeared necessary for thermal stability. Nonionic amine amphiphiles have been found to lead to less ordered zirconia mesostructures, due to the weak interaction with the zirconium n -propoxide precursor. The chain-length-independent templating ability of the amphiphiles and ex situ 31 P MAS NMR of dodecyl phosphate (before and after incorporation into Zr-TMS) supported a method of formation involving covalent-bond interactions between the headgroup and the inorganic precursor.

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.
