Abstract The simple and environmentally friendly fabrication of cost-effective nanocomposites with low-metal usage is a promising approach for high-performance supercapacitors. Most developed rely on expensive carbon materials, such as graphene nanotubes, high metal loading (> 50 wt%), complex preparation protocols. In this study, we present straightforward method fabricating noble-metal-free bimetallic trimetallic molybdates (FeMo NiCoMo) anchored heteroatom-doped hollow-core nanofibers (HCNFs). Heteroatoms B, F, N were successfully doped into the HCNFs. homogenous anchoring FeMo- or NiCoMo-oxide nanoparticles both inner outer surfaces HCNFs was confirmed—this is, to best our knowledge, first report structure. three-electrode system, NiCoMo–HCNFs demonstrated an excellent specific capacitance 1419.2 F/g retention 86.0% after 10,000 cycles. fabricated device exhibited 225.7 F/g, power density 45.5 W/kg, energy 10,089.3 Wh/kg, 86.1% For reduction 4-nitrophenol, FeMo–HCNFs achieved k app values 30.14 87.71 × 10 −2 s −1 , respectively. Due their preparation, cost-effectiveness, activity, robustness, are candidates storage environmental catalysis applications. Graphical Bimetallic Trimetallic supported fibers
