摘要：

Novel hexagonal (h)-YFeO3/alpha-Fe2O3 heterojunction composite nanowires were firstly prepared via electrospinning technique assisted with anneal treatment. The results show that the composite nanowires with a diameter of 150 nm are composed by distributed small h-YFeO3 nanograins and continuous alpha-Fe2O3 nanograins. Compared with pure h-YFeO3 and pure alpha-Fe2O3, the prepared h-YFeO3/alpha-Fe2O3 composite nanowires possess relatively higher electron-hole separation efficiency as well as photocatalytic activity of RhB degradation due to the formed heterojunctions between the h-YFeO3 nanograins and the alpha-Fe2O3 nanograins. Furthermore, the h-YFeO3/alpha-Fe2O3 composite nanowires exhibit good photocatalytic stability. At last, mechanism of enhanced photocatalysis about the h-YFeO3/alpha-Fe2O3 heterojunction is also illustrated. (C) 2015 Elsevier B.V. All rights reserved.
