Abstract:Au-modified CuFe 2 O 4 nanotubes (Au-CuFe 2 O 4 NTs) were synthesized through a combination of electrospinning and liquid precipitation methods, resulting in the uniform surface modification of well-dispersive Au nanoparticles (NPs) with an average diameter of 3.4 nm. Gas-sensing results demonstrated that the Au-CuFe 2 O 4 sensors (0.5−5 wt % Au) exhibited significantly enhanced responses to xylene gas. Specifically, the 2 wt % Aumodified sensor displayed the highest response (38.1 @ 100 ppm xylene) and excell… Show more
