Elucidation of the Activity and pH Stability Limits of Polyoxometalate-Intercalated Layered Double Hydroxide Nanocomposites toward Water Oxidation Catalysis

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

The inclusion of water oxidation active polyoxometalates (POMs) inside layered materials is a promising strategy to increase their catalytic efficiency while overcoming fragility under homogeneous conditions. In this sense, intercalation POMs in the interlaminar space double hydroxides (LDHs), formed by positively charged brucite-type inorganic layers, very interesting that gaining attention field. Despite huge potential, there lack accurate characterization materials, especially after use as catalysts pH conditions which POM counterpart has been demonstrated be unstable (strong alkali media). For reason and proof concept, we have intercalated well-known [Co4(H2O)2(PW9O34)2]10– (Co4-POM) lamellar Mg2Al-LDH, study its capabilities stability. Remarkably, nanocomposites show improved efficiencies with excellent stability close-to-neutral media compared water-insoluble cesium salt Co4-POM or commercial Co3O4. However, thorough postcatalytic demonstrates polyoxotungstate framework suffers from hydrolytic instability strong conditions, leading formation mixed-valence cobalt(II/III) oxide interlayer Mg2Al-LDH. This work highlights importance accurately assessing fate reaction, when are employed outside window POM, can lead erroneous conclusions mistaken activities.
