Deposition of ultrasmall γ-Mo2N nanocrystals on TiO2 nanowires and their promotion effect on photocatalytic activity

Mo2N decorated TiO2 nanowires were obtained via impregnating titanate nanowires with a mixture of (NH4)6Mo7O24 and hexamethylenetetramine, followed by the calcination at 600–800 oC in N2 atmosphere. The results show that only Mo6+ species can be found in the sample calcined at 600 oC while Mo elemen...

Zusammenfassung:Mo2N decorated TiO2 nanowires were obtained via impregnating titanate nanowires with a mixture of (NH4)6Mo7O24 and hexamethylenetetramine, followed by the calcination at 600–800 oC in N2 atmosphere. The results show that only Mo6+ species can be found in the sample calcined at 600 oC while Mo element is still dominantly in the form of Mo6+ with a negligible amount of γ-Mo2N (namely Moδ+, 0 ​
