Figure 2From: Ionic Liquid-assisted Synthesis of Polyaniline/Gold Nanocomposite and Its Biocatalytic ApplicationThe X-ray photoelectron spectra of the N 1s for the polyaniline/gold nanocomposite. The peak A at binding energy of 399.4 eV corresponds to the benzenoid amine (–NH–). A higher binding energy peak (Peak B) centered at 401.2 eV is also found in Au–PolyanilineBack to article page
