Abstract

Comparing to the conventional polyoxometalate (POM)-templated silver (Ag) clusters, asymmetrically covered POM-templated Ag clusters have been rarely reported. In this work, a new Ag cluster, H[Co(SiW₁₁O₃₉)Co₄(OH)₃(NO₃)₂(SiW₉O₃₄)@Ag₃₇(^tBuC[tbnd]C)₂₃(NO₃)₂(DMF)₃] (Ag₃₇Co₅), has been successfully prepared using a facile solvothermal approach. Such a unique asymmetrical architecture is ascribed to the uneven charge distribution of the in situ generated [Co(SiW₁₁O₃₉)]⁶⁻ and [Co₄(OH)₃(NO₃)₂(SiW₉O₃₄)]⁷⁻ moieties, leading to the asymmetrical coverage of alkynyl-protected Ag shell. Various physicochemical and catalytic studies revealed that the resulting solid-state Ag₃₇Co₅ crystals exhibited interesting temperature-dependent photoluminescence property, efficient and recyclable photothermal conversion ability, and good catalytic activity towards the detoxication of 4-nitrophenol.
