摘要：

Based on in situ X-ray diffraction and EXAFS studies, it is shown that NiTiO3 formed by the reaction of TiO2 (anatase) with Ni2+ during the calcination of Ni/TiO2, gives rise to Ni metal and TiO2 (rutile) on reduction, a process that may be responsible for the strong interaction between the metal and the oxide support.
