论文摘要
在Trieste（意大利）的Elettra Synchrotron（意大利）的Elettra Synchrotron运行的Istituto officina dei Mealitiali-Consiglio delle Ricerche（IOM-CNR）的高级二色症（BACH）的光束线（IOM-CNR），在极端的超级紫罗兰色（EUV）（EUV）（EUV）的X射线X射线X射线能量能量范围高度稳定范围较高的范围和较高的光度范围。梁线提供了一种多技术方法，用于研究材料的电子，化学，结构，磁性和动力学特性。最近，这三个端站之一是基于固体/液体界面和光催化或电化学反应期间的电子转移过程进行实验。在存在液体和在环境压力下的试剂气体存在下进行柔软的X射线光谱的合适细胞。在这里，我们介绍了两种类型的静态细胞在传播或荧光产量中工作，以及一个允许原位进行环状伏安法的电化学流量，在工作电极上进行电沉积（WE）并研究了operando的化学反应。提出了在环境条件下和液体电化学实验期间进行的X射线吸收光谱（XAS）测量的示例。
The Beamline for Advanced diCHroism (BACH) of the Istituto Officina dei Materiali-Consiglio Nazionale delle Ricerche (IOM-CNR), operating at Elettra synchrotron in Trieste (Italy), works in the extreme ultra violet (EUV)-soft X-ray photon energy range with selectable light polarization, high energy resolution, brilliance and time resolution. The beamline offers a multi-technique approach for the investigation of the electronic, chemical, structural, magnetic, and dynamical properties of materials. Recently one of the three end-stations has been dedicated to experiments based on electron transfer processes at the solid/liquid interfaces and during photocatalytic or electrochemical reactions. Suitable cells to perform soft X-ray spectroscopy in the presence of liquids and reagent gases at ambient pressure were developed. Here we present two types of static cells working in transmission or in fluorescence yield, and an electrochemical flow cell which allows to carry out cyclic voltammetry in situ, electrodeposition on a working electrode (WE) and to study chemical reactions in-operando conditions. Examples of X-ray absorption spectroscopy (XAS) measurements performed in ambient conditions and during electrochemical experiments in liquid are presented.
