The preparation of organically functionalised chromium and nickel nanoparticles

Abstract

Nanoparticles of chromium or nickel have been prepared by the reduction of either CrCl₂ or Ni(acac)₂ (acac = pentane-2,4-dionate) at elevated temperatures in various Lewis base solvents; the effect of the Lewis base, which acts as both a reaction solvent and passivating ligand on morphology are apparent; the nanostructures have been analysed by NMR, IR, TEM and XRD.
