Facile fabrication of Mn²⁺-doped ZnO photocatalysts by electrospinning.

ABSTRACT: In this study, a high-efficiency photocatalyst was synthesized by Mn²⁺-doped ZnO nanofibres (NFs) fabricated by facile electrospinning and a following annealing process, in which Mn²⁺ successes incorporate to ZnO NFs lattice without changing any morphology and crystalline structure of ZnO. The photodegradation properties of ZnO loading with different concentrations of Mn²⁺ (5, 10, 15 and 50 at%) were investigated. The 50% MnO-ZnO composite owns excellent active photocatalytic performance (quantum efficiency up to 7.57%) compared to pure ZnO (0.16%) under visible light and can be considered as an efficient visible light photocatalyst material. We systematically analysed its catalytic mechanism and found that the enhancement belongs to the Mn doping effect an
