Abstract:
Monodispersed Ru, Pt and Pd nanoparticles with narrow size distributions (2, 12 and 20 nm respectively) have been synthesised via bubbling hydrogen gas into aqueous solutions of the noble metal ions in the presence of p-phosphonic acid calix[8]arene, at room temperature. Molecular modelling of the Ru nanoparticles provides insight into the role of the calixarene in controlling the size and stabilisation of the metal nanoparticles.
