摘要

接触电催化（CEC）是利用接触电化（CE）过程中的电子转移来加速化学反应，作为一个新兴领域受到广泛关注。然而，究竟有多少在接触电化过程中产生的活化电子参与了接触电催化反应，还需要进行定量分析，以进一步改进接触电催化反应。因此，我们介绍了一种在不同温度和超声波条件下研究 CE 到 CEC 转化的分析方法，以及单次电荷转移循环中活化电子数量的定量指标，用于评估不同 CEC 催化剂的性能。这项研究阐明了在 CE 过程中参与 CEC 的电子比例，从而深入了解了从 CE 到 CEC 的转变过程，并有助于进一步优化 CEC 的研究。

Quantified analysis on the conversion from contact electrification to contact-electro-catalysis and the performance of contact-electro-catalysts

Contact-electro-catalysis (CEC), utilizing electron transfer during contact electrification (CE) to accelerate chemical reactions, has garnered extensive attention as an emerging field. However, how many activated electrons produced during CE participate in the CEC are necessary to be quantitatively analyzed for further improving the CEC reaction. Hence, we introduce an analytical method for investigating CE-to-CEC conversion at various temperatures and ultrasonic conditions, as well as a quantitative metric of the amount of activated electrons in a single charge transfer cycle for evaluating the performance of different CEC catalysts. This study elucidates the proportion of electrons involved in CEC during CE, which provides insights on the transition from CE to CEC, and facilitates further optimization researches for CEC.

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
