Development of in-situ cell for fluorescence-mode XAFS in BL14B2 of Spring-8

An in-situ cell for fluorescence-mode XAFS was developed in BL14B2 of SPring8. It was confirmed that the cell temperature can be up to 850 °C under atmospheric pressures of reaction gases basing on our firm tests in real experiment. The temperature stability of the cell especially at low temperature region is checked with samples of highly dispersed Pt atoms on FeOx nano-sized supporters by detecting Pt L3 and Fe K edges. The in-situ cell show very good stabilities and the projected temperature on the test position correspond well with that of TPR results.
