Improved sample environment for in situ neutron powder diffraction: Temperature calibration and simultaneous Raman spectroscopy
Solid gas reactions are getting high attention due to far-reaching applications, e. g. the synthesis of functional materials and gas storage. A sapphire single-crystal gas pressure cell has been developed and used successfully for the study of hydrogenation reactions and pathways. To maximize data quality and sample temperatures, thinner walled sample holder will be tested, reducing the contribution to the diffraction data and allowing a higher heating efficiency. Further, newly developed and validated gas pressure cells will be calibrated for the sample temperature with Pd and Si powder using a new pyrometer. Additionally, simultaneous in situ Raman spectroscopy should be coupled with in situ neutron diffraction, using sapphire single-crystal gas pressure cells. This offers a complementary technique to in situ neutron diffraction, helping distinguish functional groups in crystal structures, e.g. OH-, NH2-, NH2-. Further, amorphous intermediate phases could be characterised, enabling new science. The proposed coupling has the advantage of probing exactly the same state of matter, instead of performing two different measurements.
