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.

将合成金纳米颗粒固定在三维多孔电极上

合成的金纳米颗粒已成功固定在先前已被硫官能化的石墨毡纤维上。用于将它们束缚在表面上的官能团的性质以及嫁接到纳米颗粒上的配体的性质在固定过程中起着重要作用。这些发现为开发由具有可控化学成分，形状和大小的纳米粒子改性的三维多孔材料提供了有效的方法。
