[1] The solubility of hydrogen in Fe 2 O 3 ‐doped rutile and TiO 2 (II) at 1100°C has been experimentally determined. H incorporation in rutile is coupled to substitution of Fe 3+ onto the octahedral Ti 4+ site. In contrast, TiO 2 (II) contains no structurally‐incorporated hydrogen. The dominant Fe 3+ incorporation mechanism in both phases is unrelated to H content, and involves
