In the present study, we introduce Poly(vinylidene fluoride) (PVDF) nanofibers containing nickel (Ni) nanoparticles (NPs) as a result of an electrospinning. Typically, a colloidal solution consisting of PVDF/Ni NPs was prepared to produce nanofibers embedded with solid NPs by electrospinning process. The resultant nanostructures were studied by SEM analyses, which confirmed well oriented nanofibers and good dispersion of Ni NPs over them. The XRD results demonstrated well crystalline feature of PVDF and Ni in the obtained nanostructures. Physiochemical aspects of prepared nano-structures were characterized for TEM which confirmed nanofibers were well-oriented and had good dispersion of Ni NPs. Furthermore, the prepared nano-structures were studied for hydrogen production applications. Due to high surface to volume ratio of nanofibers form than the thin film ones, there was tremendous increase in the rate of hydrogen production. Overall, results satisfactorily confirmed the use of these materials in hydrogen production.
在本研究中，我们通过静电纺丝制备了含有镍（Ni）纳米颗粒（NPs）的聚偏氟乙烯（PVDF）纳米纤维。通常，制备一种由PVDF/Ni NPs组成的胶体溶液，通过静电纺丝工艺生产嵌入固体NPs的纳米纤维。通过扫描电子显微镜（SEM）分析对所得纳米结构进行了研究，结果证实纳米纤维取向良好，且Ni NPs在其上分散良好。X射线衍射（XRD）结果表明，所得纳米结构中PVDF和Ni具有良好的结晶特性。通过透射电子显微镜（TEM）对制备的纳米结构的物理化学特性进行了表征，结果证实纳米纤维取向良好，且Ni NPs分散良好。此外，还对制备的纳米结构进行了制氢应用研究。由于纳米纤维形态的材料比薄膜材料具有更高的比表面积，制氢速率有了极大提高。总体而言，结果令人满意地证实了这些材料在制氢中的应用。
