In Situ and Operando Capabilities
In addition to standard ex-situ Transmission and Fluorescence measurements, BL5.2 provides advanced capabilities for In-Situ and Operando XAS studies. This allows researchers to monitor the dynamic evolution of atomic structure and chemical states under realistic operating conditions.
Available Environments & Equipment:
-
High-Temperature Cells:
-
Transmission Mode: Heating up to 1,000°C.
-
Fluorescence Mode: Heating up to 600°C.
-
-
Controlled Gas System (For In-Situ Studies):
-
Designed to work in conjunction with heating cells, this system allows for the precise flow of reactive and inert gases (H₂, N₂, O₂, He, Ar, and CO₂).
-
It enables the real-time study of gas-solid interactions, particularly for Redox (Reduction/Oxidation) reactions in catalysis and advanced materials research.
-
-
In-Situ Electrochemistry:
-
Specialized electrochemical cells (typically for fluorescence mode) are available to study energy storage materials, such as batteries and fuel cells, during charge/discharge cycles.
