Abstract

The pyrolysis of several physical mixtures of AuCl(PPh ₃) with polymeric [NP(O ₂C ₁₂H ₈)] _n or cyclic N ₃P ₃(O ₂C ₁₂H ₈) ₃ phosphazenes, formed as solid powders or films with different molar ratios, have been studied under air and at 800 °C. The characterization of the products has shown that the particle size and morphology are strongly dependent on the nature of the phosphazene, the phosphazene/AuCl(PPh ₃) molar ratio and on the preparation methodology. Gold nanoparticles (NPs) with mean sizes as small as 3. 5 nm were obtained from a [NP(O ₂C ₁₂H ₈)] _n/AuCl(PPh ₃) 1:1 film. The particle morphology was also strongly dependent on the experimentally conditions of the pyrolysis. Powdered materials exhibit a 3-D irregular morphology in the mixture [NP(O ₂C ₁₂H ₈)] _n/AuCl(PPh ₃) 3:1 film, and gold foams in the 1:1 ratio, both from the [NP(O ₂C ₁₂H ₈)] _n/AuCl(PPh ₃) as well as N ₃P ₃(O ₂C ₁₂H ₈) ₃/AuCl(PPh ₃) mixtures. These results show for the first time the possibility of controlling morphology and size of gold particles obtained by solid-state reactions.
