[Analysis Case] Evaluation of the Chemical State of RuO2 Catalyst using in-situ XAFS
Measurement is possible under the specified gas atmosphere and temperature conditions.
In-situ XAFS allows for the evaluation of the chemical bonding state and local atomic structure of a sample under controlled conditions, focusing on the gas atmosphere and temperature surrounding the sample. Therefore, it is suitable for cases where state evaluation in special environments, such as catalysts, is necessary. This document presents a case where RuO2 powder was heated from room temperature to 400°C under a reducing atmosphere using in-situ XAFS, capturing the changes in the state of RuO2. From the shape of the spectrum, it was confirmed that RuO2 is reduced to Ru between 100°C and 200°C.
