Nanoparticle - Wikipedia
2020-8-7 · A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm,  or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.

2019-12-12 · We report the first synthesis of highly monodisperse Pt3Zn nanocrystals (NCs). Shape-controlled synthesis generates cubic and spherical Pt–Zn NCs. Reaction temperature is the key to incorporate Zn into Pt, even in the absence of a strong reducing agent. The Pt–Zn NCs are active toward methanol oxidation, with the spherical NCs exhibiting higher activity than the cubic NCs. The Pt–Zn
