A two-step synthesis of microsphere-decorated fibers based on NiO/ZnSnO3 composites towards superior ethanol sensitivity performance

A novel systematic heterostructures based on NiO/ZnSnO3 microsphere-decorated fibers were produced with a simple two-step process based on the electrospinning and hydrothermal procedures. A large density of NiO microspheres were homogeneously and epitaxially decorated on ZnSnO3 nanofibers. The crystal, structural and surface compositional properties of sample based on NiO/ZnSnO3 composites were investigated by XRD, SEM, TEM, EDX, XPS and BET...
