Synthesis and catalytic behavior of bimetallic nanoparticles supported on TEMPO-oxidized cellulose nanofibers

摘要

The structural and functional design of metal nanoparticles has recently allowed remarkable progress in the development of high-performance catalysts. Gold nanoparticles (AuNPs) are among the most innovative catalysts, despite bulk Au metal being regarded as stable and inactive. The hybridization of metal NPs has attracted major interest in the field of advanced nanocatalysts, due to electro-mediated ligand effects. In practical uses, metal NPs need to be supported on a suitable matrix to avoid any undesirable aggregation; many researchers have reported the potential of polymer-supported AuNPs. However, the use of conventional polymer matrices make it difficult to take full advantage of the original properties of the metal NPs, since most of active NPs are imbedded inside the polymer supports. This results in a poor accessibility for the reactants and less catalytic efficiency.
