Gold Nitride: Preparation and Properties

Abstract

We review the currently known methods of producing gold nitride and report on the influence of electrically isolated substrates on the growth of gold nitride films by reactive ion sputtering (RIS). It is found that isolation of the substrate decreases grain size and increases nitrogen content, the latter attributed to longer nitrogen ion lifetime on the surface of the growing film. The chemical reactivity of gold nitride is compared with that of pure gold films using the adsorption of 1-dodecyl mercaptan (CH 3 (CH 2 ) 11 SH) as a model system and it is found that there is no significant difference between gold films and gold nitride in terms of Au-S binding. However, gold nitride nanoparticles are suggested to be worthy of further investigation in terms of their catalytic properties.

“…The same spectra reported in Figure 2 also indicate that the adsorption of C 6 NH 2 on AuNPs does not induce side reactions, as inferred by the absence of peaks ascribed to –NO x or Au nitride species; 36 - 38 in addition, oxygen traces are absent on the surface, indicating that no oxidation processes occur. Finally, the lack of significant shift of the Au 4f core level spectra and the absence of significant shoulder located at higher binding energy with respect to a bare Au substrate suggest that the nature of the surface is not modified by the adsorption of amines.…”

“…N -(2-aminoethyl)-ferrocenecarboxamide (FcCA) was synthesized in 73% yield as already reported. 42 AuNPs surrounded by chloride anion and possessing a mean diameter of 3.5 nm have been obtained as already reported 38 and used without any further purification.…”

An Overview of the Synthesis of Gold Nanoparticles Using Radiation Technologies

“…Gold nitride, for instance, is a promising candidate for a plethora of applications, since jewelry, micro-engineering, catalysis and Raman spectrometry. These nitrides can be synthesized in different ways, with ease and good control of morphology and properties [ 24 , 25 ]. In a further section, we discuss the most important applications for the biomedical field.…”

AuN films - structure and chemical binding

“…In addition, the catalytic properties of TMNs have been reviewed with those of carbides because of their resemblance in many reactions . Because of gold nitride exhibits some catalytic performance, it may be used as a new substrate for surface‐enhanced Raman scattering experiments . Although the 4d and 5d series of transition metals (Ru, Rh, Pd, Ag, Os, Ir, Pt, and Au) have not been generally considered as candidates in nitride formation, there has been considerable effort in the last decade to obtain gold nitride thin films.…”

“…[1,2] Because of gold nitride exhibits some catalytic performance, it may be used as a new substrate for surface-enhanced Raman scattering experiments. [3,4] Although the 4d and 5d series of transition metals (Ru, Rh, Pd, Ag, Os, Ir, Pt, and Au) have not been generally considered as candidates in nitride formation, there has been considerable effort in the last decade to obtain gold nitride thin films. Gold nitride species have been produced using reactive ion sputtering, ionic implantation, arc-pulsed, and laser ablation techniques and have been observed at binding energies of 396.6 eV, 397.0 eV, and 398.1 eV using the X-ray photoelectron spectroscopy (XPS) technique.…”
