在金属表面充电和脱氢过程中，原位测量了纳米多孔金的电导率。采用从Au-Ag合金中选择性脱银的方法制备了纳米多孔金样品。通过使样品成为电化学池中的工作电极，在表面产生电荷。电导率随诱导表面电荷的变化可逆变化。
The electrical conductivity of nanoporous gold was measured in situ during the charging and decharging of the surface of the metal. The nanoporous gold samples were prepared by the process of selective dealloying of Ag from Au–Ag alloy. Charge was induced on the surface by making the sample a working electrode in an electrochemical cell. The conductivity was observed to vary reversibly with the induced surface charge.
