在这里，我们报告说，压力驱动的流动单独（没有外部电能）可以用来驱动法拉第电化学反应的微通道带电壁。具体而言，我们表明，溶液流可以产生流动电位的顺序上的伏特，这是足以进行反应的阳极和阴极的双极电极（BPE）。法拉第反应的存在被证明从BPE的阳极端的银的电溶解。
Here we report that pressure-driven flow alone (no external electrical energy) can be used to drive faradaic electrochemical reactions in microchannels with charged walls. Specifically, we show that solution flow can generate streaming potentials on the order of volts and that this is sufficient to carry out reactions on the anodic and cathodic poles of a bipolar electrode (BPE). The existence of faradaic reactions is proven by electrodissolution of Ag from the anodic end of the BPE.
