| 摘要 |
Disclosed is a complex comprising (A) cellulose nanofibers each having a carboxyl group or a carboxylate group on the surface and (B) metal nanoparticles, wherein the metal nanoparticles (B) are supported via the carboxyl group or the carboxylate group as a contact point. The complex is preferably produced through the steps of: preparing the cellulose nanofibers (A); bringing the cellulose nanofibers (A) into contact with an aqueous metal compound solution to cause the carboxyl group or the like to bind to the metal compound; and reducing the metal compound to form the metal nanoparticles. |
