Abstract

Reducing the particle size of the metal-organic frameworks (MOFs) MIL-68(In) and ZIF-8 leads to increased adsorption of volatile semiochemical guests. Opposing trends were observed in release dynamics, with the release rate of isobutyl acetate increasing with particle size for MIL-68(In) and decreasing for ZIF-8, which can be attributed to the lower diffusion barriers through channels in comparion to moving between discrete pores.

金属-有机骨架中粒径对蒸汽吸收和释放动力学的影响

减小金属有机骨架（mof） MIL-68（In）和ZIF-8的粒径会导致挥发性半化学客体的吸附增加。在释放动力学中观察到相反的趋势，MIL-68（in）的醋酸异丁酯释放速率随着粒径的增大而增大，而ZIF-8的释放速率则随着粒径的增大而减小，这可归因于与在离散孔隙之间移动相比，通过通道的扩散屏障较低。
