This study focused on the fabrication and characterization of ammonium metatungstate hydrate (AMT) combined with cobalt(III) acetylacetonate (Co(acac))-loaded electrospun micro-nanofibers. The morphologies, structures, element distribution, through-pore size, and through-pore size distribution of AMT/Co(acac)-loaded PAN/PS micro-nanofibers were investigated by a combination of field emission scanning electron microscopy (FESEM), flourier transformation infrared (FTIR) spectroscopy, energy disperse spectroscopy (EDS), through-pore size analyzer, and so on. These micro-nanofibers have many advantages in their potential application as electro-catalysts. The porous and large thorough-pore will benefit for effective electrolyte penetration, in addition to promoting gas bubbles evolving and releasing from catalyst surface timely.
本研究聚焦于水合偏钨酸铵（AMT）与负载乙酰丙酮钴（III）（Co(acac)）的电纺微纳纤维的制备与表征。通过场发射扫描电子显微镜（FESEM）、傅里叶变换红外（FTIR）光谱、能谱分析（EDS）、通孔尺寸分析仪等相结合的方法，研究了负载AMT/Co(acac)的PAN/PS微纳纤维的形貌、结构、元素分布、通孔尺寸和通孔尺寸分布。这些微纳纤维在作为电催化剂的潜在应用中具有许多优势。多孔且大的通孔有利于有效电解质渗透，此外还能促进气泡及时从催化剂表面逸出和释放。
