5TiO7” is Ni5TiO4(BO3)2]]>

摘要

Abstract It is shown that the compound known as Ni5TiO7 and considered as a promising catalyst and oxidation product of alloys does not exist and its XRD pattern actually corresponds to Ni5TiO4(BO3)2 Graphical abstract XRD pattern of “Ni5TiO7” (top) is identical to that for Ni5TiO4(BO3)2 (bottom) based on single-crystal structural data Display Omitted Highlights ? Popular catalyst known as Ni5TiO7 is actually Ni5TiO4(BO3)2. ? B2O3 came from the flux used for crystal growth. ? Some authors reporting this phase did not use any boron compounds. ]]>
