2-Methoxycycloocta-1,5-dienyl platinum complexes as precursors for platinum nanoparticles

Abstract

Thermolysis of [Pt2(μ-OR)2(C8H 12OMe)2] (R = Me or Ac) in hexadecylamine (HDA) at 210°C under argon atmosphere gave platinum nanoparticles which were characterized by XRD, EDAX and TEM analysis. Both spherical (̃ 10 nm) and rod-like (̃ 19 nm length with aspect ratio of 2.3) face centred cubic ( fcc) platinum metal nanoparticles could be isolated. The thermogravimetric analyses of these complexes revealed that they undergo a single step decomposition leading to the formation of platinum metal powder. © Indian Academy of Sciences.
