Immobilization of synthetic gold nanoparticles on a three-dimensional porous electrode

Abstract Synthetic gold nanoparticles were successfully immobilized on graphite felt fibers previously functionalized by sulfur groups. The nature of the functional groups used to tether them on the surface and the nature of the ligand grafted on nanoparticles play important roles in the immobilization process. The findings offer an effective way to develop three-dimensional porous materials modified by nanoparticles with controlled chemical composition, shape and size.
