反向电子转移，其中电子从一个阶段中具有较高的标准还原电位的氧化还原电对向上转移到另一个氧化还原电对具有较低的标准还原电位在第二不混溶相，证明使用系统TCNQ（在1，2-二氯乙烷）/亚铁氰化物（在水中）。反向电子转移的驱动力是存在适当的电位决定离子，其控制界面电位差，这反过来又决定了两相氧化还原反应中的平衡位置。通过扫描电化学显微镜监测反向电子转移的发生。
Reverse electron transfer, in which an electron is transferred uphill from a redox couple with a higher standard reduction potential in one phase to another redox couple having a lower standard reduction potential in a second immiscible phase, is demonstrated using the system TCNQ (in 1,2-dichloroethane)/ferrocyanide (in water). The driving force for the reverse electron transfer is the presence of appropriate potential-determining ions that govern the interfacial potential difference, which in turn determines the position of equilibrium in the two-phase redox reaction. The occurrence of reverse electron transfer was monitored by scanning electrochemical microscopy.
