PtO 2 -nanoparticles functionalized CuO polyhedrons for n-butanol gas sensor application
Source abstract
Abstract
Abstract The CuO polyhedrons functionalized with different amounts of PtO 2 nanoparticles were synthesized by simple two-step method. The gas sensing properties of the sensors prepared by PtO 2 functionalized CuO polyhedron were studied and compared with pure CuO sensors. The electrical sensitivity values show that the response of S2-CuO (3.5% wt PtO 2 -CuO) polyhedron is higher than that of pure CuO polyhedron in n-butanol/air atmosphere. The sensor showed excellent reproducibility and good selectivity to n-butanol gas, and its working temperature was relatively low (180 °C), and the reaction time quickly reached 2.4 s. The enhanced properties are attributed to the structure of the CuO polyhedron and the synergistic effect of CuO and PtO 2.
