Reconstruction of layered double hydroxides from calcined precursors: a powder XRD and 27Al MAS NMR study
Abstract
The reconstruction of layered double hydroxides with the hydrotalcite-like structure from material previously calcined at increasing temperatures has been studied. Both the calcination temperature and the time the samples spent equilibrating with a controlled water vapour pressure have been considered. The crystallinity of the samples and the crystalline phases formed have been assessed by powder X-ray diffraction, while the local environment of the Al ions has been probed by 27 A1 MAS NMR. It has been found that reconstruction is complete when the sample has been calcined at or below 550 °C, after 24 h rehydration, while equilibration for 3 days is adequate to reconstruct samples previously calcined at 750 °C. Only partial reconstruction is observed after calcination at 1000 °C. However, the NMR results indicate that, in all cases, some of the Al ions remain in tetrahedral sites.

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.
