通过将含有An纳米颗粒的离子液体分散在高度有序的热解石墨（HOPG）上，然后加热，将离子液体中溅射沉积的金纳米颗粒致密地固定在高度有序的热解石墨（HOPG）表面。固定化ALL粒子的密度在很大程度上取决于所使用的离子液体的种类，并且它们的尺寸由加热温度控制。所得的纳米颗粒膜是稳定的和电化学活性的氧还原。
Gold nanoparticles sputter-deposited in ionic liquids were densely immobilized on the surface of highly ordered pyrolytic araphite (HOPG) by spreading the ionic liquid containing An nanoparticles on HOPG and then heating. The density of immobilized ALL particles was greatly dependent on the kind of ionic liquid used, and their size was controlled by the heating temperature. The resulting nanoparticle films were stable and electrochemically active for oxygen reduction.
