在本研究中，我们介绍了聚偏氟乙烯（PVDF）纳米纤维含有镍（Ni）纳米粒子（NPs）的静电纺丝的结果。通常，制备由PVDF/Ni NP组成的胶体溶液以通过静电纺丝工艺产生嵌入有固体NP的纳米纤维。所得的纳米结构进行了研究，通过SEM分析，这证实了良好取向的纳米纤维和良好的分散的镍纳米颗粒在他们。XRD结果表明，所得纳米结构中PVDF和Ni具有良好的结晶特征。所制备的纳米结构的物理化学方面进行了表征，TEM证实纳米纤维是良好取向的，并具有良好的分散性的Ni NPs。此外，所制备的纳米结构进行了研究，用于制氢应用。由于纳米纤维形式比薄膜形式具有更高的表面积与体积比，因此产氢速率大大增加。总体而言，结果令人满意地证实了这些材料在氢气生产中的用途。
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.
