Polyoxometalate (POM)-Layered Double Hydroxides (LDH) Composite Materials: Design and Catalytic Applications

Abstract: Layered double hydroxides (LDHs) are an important large class of two-dimensional (2D) anionic lamellar materials that possess flexible modular structure, facile exchangeability of inter-lamellar guest anions and uniform distribution of metal cations in the layer. Owing to the modular accessible gallery and unique inter-lamellar chemical environment, polyoxometalates (POMs) intercalated with LDHs has shown a vast array of physical properties with applications in environment, energy, catalysis, etc. Here we desc… Show more

“…An important type of hydroxide that should be discussed in particular is the binary metal cation based layered double hydroxide (LDH) materials. As shown in Figure 4a, the LDH has a hydrotalcite-like crystalline structure with a general [92,[96][97][98] In addition, transition metal oxyhydroxides including CoOOH and NiOOH also have the potential of delivering high cycling lifetime in SCs. This type of material has a nonstoichiometric composition with a layered structure and a good electric conductivity due to the high oxidation states of transition metal cations, which are beneficial for fast electron and electrolyte ion transportation.…”

“…Dies führt zur Bildung einer kationischen Überschussladung innerhalb der Schichten, die durch Interkalation mobiler Anionen und Wasser zwischen den Schichten kompensiert wird. Da dieser Bereich chemisch zugänglich ist, kann ein Ionenaustausch der Originalionen mit POMs erfolgen; dies wurde genutzt, um eine Reihe industriell relevanter Katalysatoren herzustellen und komplexe katalytische Kaskaden durchzuführen . In Zukunft könnten diese Materialkonzepte für neue Anwendungen in der multifunktionalen (Elektro‐)Katalyse oder in Batterieelektroden genutzt werden.…”

“…The formation of LDH-based materials is driven by weak interlayer interactions, and as a consequence, they offer an excellent opportunity for the development of composite compounds by exchanging the anionic and solvent content of the interlayer cavities with the desirable components. For example, exploitation of supramolecular interactions between the LDH layers and POM clusters, have given a wide range of materials with interesting catalytic properties tailored for applications in epoxidations, N-oxidations and desulfurisations [88][89][90][91][92]. …”
