In this work, nanobelt mats consisting of three potential metal oxides have been produced using the electrospinning technique. An aqueous solution of cobalt acetate tetra-hydrate, copper acetate mono-hydrate, and manganese acetate tetra-hydrate was mixed with poly(vinyl alcohol) solution to prepare a sol–gel which was electrospun at 20 kV. The obtained nanofiber mats have been vacuously dried at 80 °C for 24 h and then calcined in air atmosphere at different temperatures and soaking times. The utilized physiochemical characterizations have affirmed that nanobelts composed of three oxides (Co3O4, CuO, and MnO2) can be prepared by calcination at a temperature of 600 °C for 1 h. High-resolution transmission electron microscope and selected area electron pattern images revealed good crystallinity for the synthesized nanobelts.
