Two novel polyoxometalate (POM)-encapsulated metal-organic nanotube (MONT) framework crystalline materials with unprecedented copper-mixed ligands, HUST-200 and HUST-201, have been successfully synthesized by an effective synthesis strategy. The encapsulation not only provides a shield to increase the chemical stability, but also does not affect its catalytic activity, and, therefore, the crystalline materials are very active for HER (H can diffuse easily through the pores of the MONTs). Remarkably, HUST-200 displays a low overpotential of 131 mV (catalytic current density is equal to 10 mA·cm). This work thus offers a new way for devising HER electrocatalysts with low cost using POM-encapsulated MONT frameworks.
两种新型的多酸（POM）封装的金属-有机纳米管（MONT）框架结晶材料，具有前所未有的铜混合配体，HUST-200 和 HUST-201，已通过有效合成策略成功合成。封装不仅提供了增加化学稳定性的屏蔽，而且不影响其催化活性，因此，结晶材料对 HER（H 可以很容易地通过 MONT 的孔扩散）非常活跃。值得注意的是，HUST-200 显示出 131 mV 的低过电势（催化电流密度等于 10 mA·cm）。因此，这项工作为使用 POM 封装的 MONT 框架设计低成本的 HER 电催化剂提供了一种新方法。
