Au-modified CuFe2O4 nanotubes (Au-CuFe2O4 NTs) were synthesized through a combination of electrospinning and liquid precipitation methods, resulting in the uniform surface modification well-dispersive Au nanoparticles (NPs) with an average diameter 3.4 nm. Gas-sensing results demonstrated that Au-CuFe2O4 sensors (0.5–5 wt % Au) exhibited significantly enhanced responses to xylene gas. Specifically, 2 sensor displayed highest response (38.1 @ 100 ppm xylene) excellent selectivity at 260 °C. The comprehensive influences ambient humidity content on detection capability using NTs discussed systematically. superior activity compared pristine was confirmed by their improved recovery characteristics presence high concentration xylene. These sensing performances can be mainly attributed electronic sensitization synergistic catalytic effect CuFe2O4, indicating great potential for sensitive selective detection.
