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.
