A highly performing proton conducting composite was prepared through the impregnation of EMIMCl ionic liquid in the mesoporous MIL-101(Cr)-SOH MOF. The resulting EMIMCl@MIL-101(Cr)-SOH composite displays high thermal and chemical stability, alongside retention of a high amount of EMIMCl even at temperatures as high as 500 K, as well as under moisture conditions. Remarkably, this composite exhibits outstanding proton conductivity not only at the anhydrous state ( = 1.5 × 10 S cm) but also under humidity ( ≥ 0.10 S cm) conditions. This makes EMIMCl@MIL-101(Cr)-SOH a unique candidate to act as a solid state proton conductor for PEMFC applications under versatile conditions.
通过将EMIMCl离子液体浸渍在介孔MIL-101(Cr)-SOH金属有机框架中制备了一种高性能的质子传导复合材料。所得的EMIMCl@MIL-101(Cr)-SOH复合材料表现出高热稳定性和化学稳定性，即使在高达500 K的温度以及潮湿条件下，仍能保留大量的EMIMCl。值得注意的是，这种复合材料不仅在无水状态下（σ = 1.5 × 10⁻³ S cm⁻¹）表现出出色的质子传导率，而且在湿度条件下（σ ≥ 0.10 S cm⁻¹）也表现出色。这使得EMIMCl@MIL-101(Cr)-SOH成为在多种条件下用作质子交换膜燃料电池（PEMFC）应用的固态质子导体的独特候选材料。
