AB - Zn1 − xCox Zeolitic Imidazolate Framework (ZIF) (x = 0~0.05) were prepared by the co-precipitation of Zn 2+ and Co 2+ using 2-methylimidazole, which were converted into pure and Co-doped ZnO nanoparticles by heat treatment at 600 o C for 2 h.
Homogeneous Zn/Co ZIFs were achieved at x < 0.05 owing to the strong coordination of the imidazole linker to Zn 2+ and Co 2+ , facilitating atomic-scale doping of Co into ZnO via annealing. By contrast, heterogeneous Zn/Co ZIFs were formed at x ≥ 0.05, resulting in the formation of Co3O4 second phase. To investigate the potential as high-performance gas sensors, the gas sensing characteristics of pure and Co-doped ZnO nanoparticles were evaluated. The sensor using 3 at% Co-doped ZnO exhibited an unprecedentedly high response and selectivity to trimethylamine, whereas pure ZnO nanoparticles did not. The facile, bimetallic ZIF derived synthesis of doped-metal oxide nanoparticles can be used to design high-performance gas sensors.
