Abstract

Electrocatalysts play a critical role in various energy conversion and storage technologies, including fuel cells, electrolyzers, and batteries. However, finding the optimal electrocatalyst for a specific reaction is a challenging and time-consuming task, as there are many possible materials and compositions to explore. Bipolar electrode (BPE) arrays are a promising technique for high-throughput screening of electrocatalysts, as they allow simultaneous testing of multiple candidates under identical conditions without external wiring. This mini-review summarizes recent advancements and current challenges in developing and applying BPE arrays for electrocatalyst screening. We discuss the design and fabrication of BPE arrays, the methods for depositing electrocatalysts on BPEs. We also highlight some examples of BPE arrays for screening electrocatalysts for various reactions, such as oxygen reduction, hydrogen evolution, and organic oxidation. We conclude with some perspectives and suggestions for future research directions in this emerging field.

双极电极阵列高通量电催化剂筛选：综述

电催化剂在各种能量转换和存储技术中起着至关重要的作用，包括燃料电池、电解槽和电池。然而，寻找特定反应的最佳电催化剂是一项具有挑战性和耗时的任务，因为有许多可能的材料和成分需要探索。双极电极（BPE）阵列是一种很有前途的高通量电催化剂筛选技术，因为它们可以在相同的条件下同时测试多个候选物，而无需外部布线。本文综述了BPE阵列在电催化剂筛选方面的最新进展和面临的挑战。我们讨论了BPE阵列的设计和制造，以及在BPE上沉积电催化剂的方法。我们还重点介绍了BPE阵列用于筛选各种反应的电催化剂的一些例子，例如氧还原，析氢和有机氧化。最后，对这一新兴领域未来的研究方向提出了展望和建议。图形抽象
