Parallel screening of electrocatalyst candidates using bipolar electrochemistry.

Bipolar electrodes for rapid screening of electrocatalysts.

We report a method for rapid screening of arrays of electrocatalyst candidates. The approach is based on simultaneous activation of the oxygen reduction reaction (ORR) and Ag electrodissolution at the cathodic and anodic poles, respectively, of bipolar electrodes (BPEs). Because the electrochemical activity of the two poles is directly coupled via the BPE, the extent of Ag electrodissolution is...

Paper-Based Bipolar Electrochemistry

We demonstrate that carbon electrodes screen-printed directly on cellulose paper can be employed to perform bipolar electrochemistry. In addition, an array of 18 screen-printed bipolar electrodes (BPEs) can be simultaneously controlled using a single pair of driving electrodes. The electrochemical state of the BPEs is read-out using electrogenerated chemiluminescence. These results are importan...

Fabrication of gradient polymer surfaces using bipolar electrochemistry

This report focuses on recent developments using bipolar electrochemistry as an effective tool for the fabrication of gradient polymer surfaces. The electrochemical doping and reactions of conducting polymers under an applied potential distribution using bipolar electrodes have been carried out to prepare conducting polymers with composition gradients. Indirect electrolysis using an electrogene...

Bipolar electrodes: a useful tool for concentration, separation, and detection of analytes in microelectrochemical systems.

Over the past decade, bipolar electrochemistry has emerged from relative obscurity to provide a promising new means for integrating electrochemistry into lab-on-a-chip systems. This article describes the fundamental operating principles of bipolar electrodes, as well as several interesting applications.
