Electrochemical techniques have been essential to many areas of science in recent decades and are currently in the spotlight due to energy transition initiatives. Several fields are actively pursuing decarbonization technologies like green hydrogen production, carbon dioxide electroconversion, batteries, fuel cells, and others . Although the integration of various disciplines promotes scientific advancement, the inherent power and apparent simplicity of electrochemical techniques can occasionally lead to misunderstandings or misinterpretations of the results . These techniques stand out for their unique ability to easily investigate the reactions that take place at interfaces. While the last sentence is usually accepted with ease, the processes to achieve this are much deeper and, honestly, go beyond the scope of this text. Interest readers can find detailed explanations in standard electrochemistry textbooks, but here is a spoiler: it is not actually possible to measure the potential of a single interface experimentally. In essence, when attempting to measure the potential value of a specific interface A, you inadvertently introduce another interface B, resulting in the measurement of a potential difference between the two (A-B). To circumvent this challenge, we rely on a remarkable yet sometimes underappreciated tool: the reference electrode. The use of a reference electrode (as interface B) allows you to have an interface that, ideally, does not accumulate charge. Voilà! Now your introduced interface B can serve as zero background, enabling the assessment of the relative potential value of the interface A.
