Unraveling the temperature-dependent redox cycle of chromium species in molten chloride salt via in situ X-ray absorption spectroscopy

Year: 2026

Type: article

Abstract: In situ X-ray absorption spectroscopy reveals an impurity-mediated Cr redox cycle in LiCl–KCl: Cr( ii ) is oxidized to Cr( iii ) with H 2 evolution at high temperature and reduced back to Cr( ii ) by H 2 during solidification.
