摘要
准确测定电极表面的温度动态对于推进电催化技术,尤其是开发有助于能量转换和储存技术的稳定材料至关重要。在此,我们使用基于镧系元素的原位发光测温法来探测碱性水电解过程中铂电极表面的局部热效应。研究表明,在相同的电化学条件下,氧进化反应(OER)比氢进化反应(HER)引起的温度升高更为显著。这种差异归因于过电位加热的变化和焦耳加热的局部效应。此外,在 HER 反应过程中,电解质浓度增加时未观察到局部热效应,而在电解质浓度较高的 OER 反应中,则检测到了较大的温度变化(高达 2 K)。我们的观察结果凸显了原位发光测温法测量电催化反应过程中界面温度效应的潜力。
Luminescence Thermometry Probes Local Heat Effects at the Platinum Electrode Surface during Alkaline Water Electrolysis
Accurate determination of the temperature dynamics at the electrode surface is crucial for advancing electrocatalysis, particularly in the development of stable materials that aid energy conversion and storage technologies. Here, lanthanide-based in situ luminescence thermometry was used to probe local heat effects at the platinum electrode surface during alkaline water electrolysis. It is demonstrated that the oxygen evolution reaction (OER) induces a more significant temperature increase compared to the hydrogen evolution reaction (HER) under the same electrochemical conditions. This difference is attributed to variations in overpotential heating and local effects on Joule heating. Furthermore, local heat effects are not observed at increased electrolyte concentrations during the HER, whereas substantial temperature variations (up to 2 K) are detected for the OER at higher electrolyte concentrations. Our observations highlight the potential of in situ luminescence thermometry to measure interfacial temperature effects during electrocatalytic reactions.
