Cover Feature: In Situ X‐ray Diffraction Studies on the Reduction of V ₂ O ₅ and WO ₃ by Using Hydrogen (Chem. Eur. J. 17/2023)

The reduction of V2O5 and WO3 with hydrogen, the latter of which is performed industrially in rotary kilns under a hydrogen countercurrent, has been investigated by using in situ X-ray powder diffraction. This method yields insights into the processes illustrated by the transparent section of the furnace, thus gaining information about the reaction pathways as well as compositions and structures of intermediates. More information can be found in the Research Article by H. Kohlmann and co-workers (DOI: 10.1002/chem.202203932).
