Abstract
The direct growth of Metal-Organic-Frameworks (MOFs) on ceramic substrates is a promising strategy to promote their industrial implementation. Yet, the lack of deep scientific comprehension regarding the in-situ conversion of metal derivatives into MOFs, resulting in limited control over their crystal growth, morphology and distribution, hampers their up-scale production. In this work, we provide for the first time the experimental evidence that a competition between MOF formation and alumina facet rearrangement occurs at extended reaction times up to 90 min. We demonstrate that the facet rearrangement induced by pH variations dictates the final morphology and distribution of MOF(Al) crystals grown during the MW-assisted hydrothermal synthesis in water. Hence when facet-rich alumina substrate is used for oxide-to-MOF conversion, short reaction times ought to be applied.
期刊介绍:
Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials.
Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
