Silver nanoparticle formation on lignin and two of its precursors : research data underlying the article

Dahle, Sebastian (author), Wegewitz, L. (author), Viöl, Wolfgang (author), Maus-Friedrichs, Wolfgang (author)

Metastable Induced Electron Spectroscopy, Ultraviolet Photoelectron Spectroscopy (He I and He II), X-ray Photoelectron Spectroscopy, and Atomic Force Microscopy were employed to study the interaction of silver with lignin as well as with two of its natural precursors coniferyl alcohol and sinapyl alcohol. For all three of them, no chemical interaction between the adsorbed silver and the organic substrate was found in the first place. Nevertheless, silver nanoparticles were found in all three cases after contact with air. Thus, a decomposition process is suggested, similar to the previously found catalytic decomposition of cinnamyl alcohol by water in the presence of silver atoms.

Abstract

Metastabilna elektronska spektroskopija, ultravijolična fotoelektronska spektroskopija (He I in He II), rentgenska fotoelektronska spektroskopija in mikroskopija z atomsko silo so bili uporabljeni za preučevanje interakcije srebra z ligninom ter z njegovima naravnima predhodnikoma koniferil alkohol in sinapil alkohol. Pri vseh treh ni bilo ugotovljene kemijske interakcije med adsorbiranim srebrom in organskim substratom. Kljub temu so bili v vseh treh primerih po stiku z zrakom najdeni nanodelci srebra. Tako je predlagan postopek razgradnje, podoben predhodno ugotovljenemu katalitskemu razkroju cimetovega alkohola z vodo v prisotnosti atomov srebra.
