AI Article Synopsis
- The thermal behavior of nanoporous iron(III) terephthalate (MIL-53) differs significantly from its chromium and aluminum counterparts, which expand when dehydrated.
- In the case of iron, the dehydration process is reversible and involves transitioning from a distorted, unstable anhydrous phase to a more organized structure at temperatures above 423 K.
- Throughout this transition, the pore volume of the iron-based material remains nearly constant, indicating a unique stability compared to other metal analogues.
Article Abstract
The thermal behaviour of the nanoporous iron(iii) terephthalate MIL-53 is in stark contrast to its chromium and aluminium analogues which show an expansion of the cell during dehydration; with iron, reversible dehydration occurs via evolution of the structure through a highly distorted metastable anhydrous phase to a more regular phase above 423 K in which pore volume remains approximately constant.
