Abstract Electrospun Mn1−xZnxMoO4 nanofibers (x = 2.5%, 5% and 10%), have been prepared by controlling the Zn concentration of a polymeric solution followed by calcination. The effects of Zn doping on structural, morphological, chemical characterization, and optical properties of the manganese molybdate nanofibers were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy dispersive analysis of X-rays (EDAX), BJH pore size and volume analysis, Fourier Transform Infrared (FTIR), and Reflectance spectrum in the wave length range of 200–1200 nm. XRD studies revealed the diffraction peaks are mainly assigned to the orthorhombic structure of the MoO3 phase. The microstructural investigation of the calcinated nanofibers has been achieved from the size-strain plot (SSP) model using X-ray diffraction profile analysis. The SEM images exhibit Zn-doped manganese molybdate ceramic nanofibers with diameters ranged from 60 ± 10 to 90 ± 10 nm after calcination at 400 °C. The optical property of the prepared nanofibers was also proposed according to the Kramers-Kronig model.

电纺 Mn 1-x Zn x MoO 4（x=2.5、5 和 10% Zn）纳米纤维的制备：微观结构参数、表面形态和 Kramers-Kronig (KK) 分析

摘要 电纺 Mn1−xZnxMoO4 纳米纤维（x = 2.5%、5% 和 10%）是通过控制聚合物溶液的 Zn 浓度然后煅烧制备的。通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、X 射线能量色散分析 (EDAX) 表征了 Zn 掺杂对钼酸锰纳米纤维的结构、形态、化学表征和光学性能的影响。 BJH 孔径和体积分析、傅里叶变换红外 (FTIR) 和 200-1200 nm 波长范围内的反射光谱。XRD 研究表明衍射峰主要归因于 MoO3 相的正交结构。已使用 X 射线衍射剖面分析从尺寸应变图 (SSP) 模型中实现了煅烧纳米纤维的微观结构研究。SEM 图像显示出 Zn 掺杂的钼酸锰陶瓷纳米纤维，在 400 °C 下煅烧后直径范围为 60 ± 10 至 90 ± 10 nm。根据 Kramers-Kronig 模型还提出了制备的纳米纤维的光学性质。
