Abstract

This is a study reporting the one-pot synthesis of gold nanoparticles/TEMPO (2,2,6,6-Tetramethylpiperidine-1-oxyl) cellulose nanofibers (CNF) nanocomposites through facile direct current atmospheric pressure microplasma (APM) technology. Compared to conventional synthetic approaches, the APM process is fast (within minutes), energy-efficient and eliminates the use of harsh chemicals. To reveal the impact of APM processing and effect of gold salt precursor concentration on the resulting materials structures and properties, comprehensive characterization (such as ultraviolet-visible (UV-vis) spectroscopy, XRD, XPS, and TEM) has been carried out. In addition, density functional theory (DFT) calculation was carried out to reveal the interfacial interaction mechanism between gold nanoparticles and the TEMPO-cellulose nanofibers. Finally, the potential of the resulting nanocomposite as SERS substrates was demonstrated using methylene blue as model analyte.
