Abstract

Copper oxide-doped alumina nanofibres were fabricated by the solution combustion method. The bundled alumina nanofibres were impregnated with a copper nitrate–glycine (oxidizer–fuel) solution and heat-treated in an open-air environment at 400 °C for 30 min. The microstructure and phase composition of the final product were characterized by XRD, SEM, and EDS analyses. A uniform distribution of a fine-grained CuO film on the surface of gamma-alumina nanofibres was revealed. The obtained results showed a dramatical effect of the amount of fuel, the ratios of fuel to oxidizer and fibres to Cu(II) ions in the reaction mixture on the particle size of the combustion product, its phase composition, and microstructure morphology.
