چکیده انگلیسی
The CuO polyhedrons functionalized with different amounts of PtO2 nanoparticles were synthesized by simple two-step method. The gas sensing properties of the sensors prepared by PtO2 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 PtO2-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 (180â¯Â°C), and the reaction time quickly reached 2.4â¯s. The enhanced properties are attributed to the structure of the CuO polyhedron and the synergistic effect of CuO and PtO2.
