(author) Chromium promotion of iron oxide based water-gas shift (WGS) catalysts prepared via co-precipitation/calcination was investigated. Mössbauer spectroscopy and XRD evidence that chromium is incorporated in the calcined hematite (α-Fe<sub>2</sub>O<sub>3</sub>) precursor irrespective of the doping level (0−12 wt.%). CO-TPR shows chromium delays...
