Atom-Precise Polyoxometalate-Ag2S Core-Shell Nanoparticles.

Atomically precise polyoxometalate-Ag₂S core-shell nanoparticles were generated in a top-down approach under solvothermal conditions and structurally confirmed by X-ray single-crystal diffraction as an interesting core-shell structure comprising an in situ generated Mo₆O₂₂⁸⁻ polyoxometalate core and a mango-like Ag₅₈S₃₈ shell. This result demonstrates the possibility to integrate polyoxometalate and Ag₂S nanoparticles into a core-shell heteronanostructure with precisely controlled atomical compositions of both core and shell.
