Fig. 1: Oxidative dispersion of AgNWs.
From: In situ identification of the metallic state of Ag nanoclusters in oxidative dispersion
a Scheme for the preparation of AgNWs onto Si3N4 (Ag/Si3N4) and the subsequent oxidation treatment (Ag/Si3N4-O-673). b, c SEM images of Ag/Si3N4 and Ag/Si3N4-O-673 samples. The scale bar in the insets is 200 nm. d HAADF-STEM image of Ag/Si3N4-O-673. e XPS Ag 3d spectra and f Ag 3d5/2 BE shift, Ag/Si ratio, and Auger parameter deduced from quasi in situ XPS data of Ag/Si3N4 and Ag/Si3N4-O-673 samples.
