Numerous chemical reactions involve oxidation or reduction and proceed via radical intermediates, and a detailed understanding of their mechanism can result in a better design of catalysts, including biomimetic systems based on redox-active enzymes. Despite the success of film electrochemistry and electron paramagnetic resonance (EPR) spectroscopy to investigate the reaction thermodynamics/kinetics and nature/structure of radical intermediates, respectively, until recently the combination of the two techniques had not been explored. Building on proof of concept studies, this project will harness the full potential of film-electrochemical EPR by investigating novel electrode materials and applying and designing new spectroscopic methods.

许多化学反应涉及氧化或还原，并通过自由基中间体进行，对其机制的详细了解可以导致更好的催化剂设计，包括基于氧化还原活性酶的仿生系统。尽管薄膜电化学和电子顺磁共振（EPR）光谱分别成功地研究了自由基中间体的反应热力学/动力学和性质/结构，但直到最近才探索了这两种技术的结合。在概念验证研究的基础上，该项目将通过研究新型电极材料以及应用和设计新的光谱方法来充分利用膜电化学EPR的潜力。
