Recently, the metal organic frameworks (MOFs) structure is concerned by its unique porous structure and regular morphology. In this paper, ZnO has been prepared by calcining MOF-5 precursors which obtained via a solvothermal method. For a better comparison, the reaction time needs to be appropriately changed to control the sizes of samples. The obtained samples were analyzed for composition and morphology by a series of characterization methods, and the results showed that particle size of MOF-5 precursors increased with reaction time. The ZnO particles formed after calcination are composed of crystal grains of 20–30 nm and thus have a porous structure. Gas-sensitive performance tests show that the sensor based on MOF-5-derived ZnO has good gas sensitivity. Among them, the responsiveness of MOF-5-derived ZnO prepared by solvothermal reaction for 4 h was the highest at 300 °C, and the response value to 100 ppm triethylamine (TEA) was 120.6. In addition, MOF-5-derived ZnO has better selectivity and repeatability than ZnO which is prepared using other methods.
