| description | Volatile Organic Compounds (VOCs) are significant contributors to air pollution and play a crucial role as precursors for secondary pollutants such as O3, thereby posing severe health risks and attracting global attention. ZIF-67, a metal-organic framework (MOFs), possesses a porous microstructure and high specific surface area, offering exceptional adsorption performance, catalytic activity, and structural stability. In this investigation, a solvent-thermal method was employed to synthesize a series of Fe-modified ZIF-67 denoted as FCMx. The impact of Fe doping and temperature on the dynamic adsorption performance of toluene was examined. The results revealed satisfactory adsorption performance of FCMx when the Fe doping was 14 mol%. FCM14 achieved saturation adsorption of toluene in approximately 5000 s, exhibiting a saturated adsorption capacity of 1769.80 mg/g at 25 °C. This represented a 25% improvement in adsorption time and a 30% increase in saturated adsorption capacity compared to undoped ZIF-67. Furthermore, at a reaction temperature of 150 °C, FCM14 exhibited saturation time of approximately 4300 s and a saturated adsorption amount of 1471.43 mg/g, indicating a combined effect of chemical and physical adsorption. The findings of this research provide valuable experimental data and theoretical support for the potential industrial application of MOFs in VOC adsorption. |
