Enhancing Catalytic Formaldehyde Oxidation on CuO-Ag2O Nanowires for Highly Sensitive Gas Sensing
CuO-Ag2O nanowires are fabricated directly on the surface of AgCuZn alloy via a facile method.Further,the prepared CuO-Ag2O nanowires display an improved electrocatalytic oxidation of formaldehyde to formate at room temperature.The constructed gas sensor exhibits an ultrahigh sensitivity of 52.40 μA ppm-1 cm-2 with a detection limit of 20.94 ppb,as well as the response and restoring time are2~5 s and 4~6 s,respectively.Here we report alloyed oxide nanostructures fabrication would supply a way for facile obtaining high performance catalytic materials.
