Visible Light Induced Ag–Polyoxometalate Coassembly into Single‐Cluster Nanowires

Abstract 1D superlattices with long‐ranged periodicity present extraordinary application properties due to their unique electronic structures. Here, the visible light driven synthesis of 1D single‐cluster chains constructed by polyoxometalate (POM) and Ag clusters is reported, where two types of clusters align alternatively along the nanowire. Low symmetrical POM clusters of [P₂W₁₇O₆₁]^10–, [P₂W₁₅O₅₆]^12–, and [EuW₁₀O₃₆]^9– can be used as building blocks. The directly bonding cluster units result in interactive electronic structures of Ag and POM clusters, as well as the greatly promoted electron transfer during the redox reaction. The Ag–P₂W₁₇ nanowires perform significantly enhanced activities in both electrochemical sensing and catalytic gasoline desulfurization compared with individual building blocks, demonstrating the extraordinary application properties and promising potentials of cluster‐based heteroconstructions.
