N2 - Nanoscale transition metal tellurides are important materials for a variety of applications. However, solution-phase methods to synthesize nanoscale transition metal tellurides are not as well-developed as for related sulfide and selenide systems. Here, we show that pre-formed colloidal metal nanoparticles react with bis(trimethylsilyl)telluride to form their corresponding tellurides. Nanoparticles of Pd, Pt, and Ni convert to nanoscale particles of the layered transition metal dichalcogenides PdTe2, PtTe2, and NiTe2 upon reaction with bis(trimethylsilyl)telluride. When Pd nanoparticles instead react with a TOP-Te complex (TOP = trioctylphosphine), PdTe forms. This result demonstrates that the metal telluride phase that forms can be controlled by the reactivity of the tellurium reagent. Other nanoparticles, including Co, Ag, and Rh, also form crystalline metal tellurides upon reaction with bis(trimethylsilyl)telluride, which indicates that this approach to synthesizing nanoscale transition metal tellurides is general.
