This study investigates the thermal evolution of ZnAl LDH ([Zn<sup>2+</sup><sub>2</sub>Al<sup>3+</sup>(OH)<sub>6</sub>]<sup>+</sup> [CO<sub>3</sub><sup>2-</sup><sub>0.5</sub>]<sup>-</sup>) using <i>in situ</i> scanning nanobeam electron diffraction, high-resolution transmission electron microscopy, and energy-dispersive X-ray analysis. The structural and morphological changes are examined during heating in both ambient air and vacuum. The pristine ZnAl LDH exhibited edge dislocations and irregular interlayer distances, leading to significant diffuse scattering in the electron diffraction patterns. Both upon heating in ambient air conditions and in vacuum, the characteristic hexagonal LDH morphology transformed into a porous nanostructure. The exact crystal structure transitions differed as a function of the environment. Heating under vacuum conditions first led to a ZnAl<sub>2</sub>O<sub>4</sub> phase with a spinel-type structure, and subsequently to ZnO particles embedded within an Al<sub>2</sub>O<sub>3</sub> matrix. When heated in a closed cell filled with ambient air, the LDH initially transitioned to an Al-doped ZnO-type structure, followed by conversion to a ZnAl<sub>2</sub>O<sub>4</sub> phase. This study is the first gas <i>in situ</i> TEM LDH study and shows the recrystallization behavior of the LDH into the different phases upon heating and uncovers the nanoscale distribution of these phases within the particles, forming ZnAl<sub>2</sub>O<sub>4</sub>, ZnO, and Al<sub>2</sub>O<sub>3</sub> composites.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"38587-38596"},"PeriodicalIF":8.3,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
