Introduction:
Electrochemical operando Cell (EC-TXAS-VI) is a unique operando cell for synchrotron radiation X-ray absorption spectroscopy characterization in the electrochemical field. This type of operando cell is optimized on the EC-TXAS-V model cell. This type cell have two advantages: 1. it is suitable for both fluorescence and transmission modes of XAFS characterization; 2. The thickness of the liquid can be adjusted properly. This is very important for different groups’ demand.
Main features:
An in-situ cell for following operando electrochemical reactions using x-ray absorption in transmission or fluorescence mode.
- It is a 3 electrode cell: the reference and counter electrodes can be replaced depending on the users’ demand. The working electrode is customized carbon.
- The cell can be divided internally
...
The operando cell is a customized electrochemical cell, which can be applied into two detect modes (fluorescence and transmission mode) for X-ray absorption spectrum characterization.
...
The operando cell can collect the operando XAFS data during the electrochemical reaction.
...
The operando cell can be applied in the both Lytle and solid-state detector even in the fluorescence mode.
...
- into two parts, and an ion-exchange membrane can be added between them to realize the function of H-type cell.
...
Inlet and outlet valves are installed in the two pools to meet the requirements of different atmospheric conditions and tightness of electrochemical reactions.
...
The whole installation of the cell is simple and fast, and the cleaning of each component is convenient.
- It has a gas inlet an outlet for analysis of reaction products.
- The cell is made of PEEK, and the thickness of the liquid
...
- can be adjusted to meet different
...
- requirements
...
Sample size can be adjusted (> φ10mm) for easy disassembly.
...
The kinds and sites of electrodes, including the reference electrode and the counter electrode, can be replaced depending on the users’ demand. The working electrode is customized carbon electrode.
...
Optical window can be made of various materials: Kapton film, high purity beryllium window and organic window.
...
Fluorescence mode window size: φ15 mm; 45 degree angle with X-ray incident light.
- .
- The optical window material can be varied to suit the experiment (kapton, beryllium, etc.).
Optional accessories: Kapton film, high purity beryllium window, other types of optical windows.
