Physical synthesis methodology and enhanced gas sensing and photoelectrochemical performance of 1D serrated zinc oxide–zinc ferrite nanocomposites

摘要: We successfully prepared one-dimensional ZnO–ZnFe2O4 (ZFO) heterostructures for acetone gas-sensing and photoelectrochemical applications, by using sputter deposition of ZFO crystallites on ZnO nanostructure templates. The nanoscale were homogeneously coated the surfaces nanostructures. Electron microscope images revealed that ZnO–ZFO exhibited a serrated surface morphology. Coating nanostructures with aggregated layer appreciably enhanced their capability at 250 °C in comparison pure presence many depleted crystallites, rugged heterostructures, electron depletion ZnO/ZFO interface might contribute to response. Furthermore, larger area higher light absorption relative correlated substantial enhancement photocurrent value tests produced simulated solar irradiation.
