An unprecedented fully reduced {Mo^V₆₀} polyoxometalate: from an all-inorganic molecular light-absorber model to improved photoelectronic performance

Abstract

Fully reduced polyoxometalates are predicted to give rise to broad and strong absorption spectrum, suitable energy levels, unparalleled electronic and optical properties, however, they are not available to date. Here,...

Platonic and Archimedean solids in discrete metal-containing clusters

“…9–11) core–shell-type {Mo 60 } (Fig. 9), 121 cubic-box-shaped {Mo 64 Ni 8 Ln 6 } (Fig. 10), 31 {Mo 84 } (Fig.…”

“…9b) polyoxomolybdate to date, which is a good all-inorganic light-absorbing material with efficient improved photo-electronic performance. 121 Mo 60 with T d symmetry can be described as one ε-Keggin Mo 12 (truncated tetrahedron) encapsulated in an unprecedented Mo 24 cage, which is further face-capped and surrounded by four tripod-shaped {Mo 6 } motifs. In addition, the whole structure of Mo 60 (Fig.…”

Constructing a Photocatalyst for Selective Oxidation of Benzyl Alcohol to Benzaldehyde by Photo-Fenton-like Catalysis

“…The Dawson-type polyanion [P 2 W 18 O 62 ] 6– with high proton-coupled electron redox activity can reversibly accept up to 18 protons and electrons in an aqueous solution . The resulting reduced POMs, called heteropoly blues, served as a rich “blue electron” storage library . Thus, unparalleled electronic and optical properties make heteropoly blues popular materials for photosensitizers or co-sensitizers during photochemical catalysis .…”

“…28 The resulting reduced POMs, called heteropoly blues, served as a rich "blue electron" storage library. 29 Thus, unparalleled electronic and optical properties make heteropoly blues popular materials for photosensitizers or co-sensitizers during photochemical catalysis. 30 Therefore, the introduction of Dawson-type polyanion into an MOF provides a promising strategy for further enhancing the photocatalytic activity.…”

Proton-Conductive Polyoxometalate Architectures Constructed from Lanthanide-Incorporated Polyoxoniobate Cages

“…POM cage-based extended materials are of special interest because such materials can not only inherit the structural characteristics and nature of the POM cages but also show unique properties derived from the infinite architecture, which exhibits broad applications in energy storage and conversion, host–guest chemistry, molecular recognition, and so on. − For instance, a series of extended POM frameworks based on POTs/POMos/POVs cages have been made in recent years. ,− By contrast, extended POM materials based on PONb cages remain largely unexplored. So far, only two kinds of PONb cage-based architectures have been reported.…”
