零排放的氢气和氧气生产对于英国到2050年实现净零温室气体排放至关重要。电化学技术，如水分解（电解）与可再生能源相结合，可以提供一种实现零排放的独特方法。许多探索电催化剂的研究需要“电线”到它们的材料来测量它们的性能，这通常涉及固定在固体电极上。我们表明，显着差异，在计算的起始电位的析氢反应（HER）和析氧反应（OER）时，可以观察到使用丝网印刷电极（SPE）的不同连接长度固定与一系列的电催化剂。这可能导致不同电催化剂的报告性能的虚假改进和文献之间的不良比较。通过使用电化学阻抗谱，可以克服未补偿的欧姆电阻，提供更准确的塔菲尔分析。
Zero-emission hydrogen and oxygen production are critical for the UK to reach net-zero greenhouse gasses by 2050. Electrochemical techniques such as water splitting (electrolysis) coupled with renewables energy can provide a unique approach to achieving zero emissions. Many studies exploring electrocatalysts need to “electrically wire” to their material to measure their performance, which usually involves immobilization upon a solid electrode. We demonstrate that significant differences in the calculated onset potential for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) can be observed when using screen-printed electrodes (SPEs) of differing connection lengths which are immobilized with a range of electrocatalysts. This can lead to false improvements in the reported performance of different electrocatalysts and poor comparisons between the literature. Through the use of electrochemical impedance spectroscopy, uncompensated ohmic resistance can be overcome providing more accurate Tafel analysis.
