Herein, a new type of multiwalled carbon nanotube anchored on hierarchically porous metal–organic framework (MOF)‐derived bimetallic phosphide composites (M16‐ZIF‐67‐CNT‐P) is reported, which is calcined from the 16‐nuclear calixarene‐based clusters together with typical ZIF‐67 polyhedra through a stepwise pyrolysis strategy. The as‐obtained M16‐ZIF‐67‐CNT‐P sample possesses large specific surface area, quick ion diffusion, high electrical conductivity, and abundant exposed active sites, which exhibits the highest electrocatalytic capability in comparison with the control counterparts. Meanwhile, this type of nanocomposite possesses a superb anodic oxygen evolution reaction (OER) performance requiring 260 mV for 10 mA cm⁻². Overall, MOF‐impregnated clusters–derived M16‐ZIF‐67‐CNT‐P exhibits an efficient water splitting performance. This method can be further extended into other systems of high‐nuclear clusters with MOF materials for energy conversion and storage applications.

金属-有机框架-浸渍的杯芳烃基团簇状多孔双金属磷化物纳米复合材料，用于高效水分解

本文报道了一种新型的多壁碳纳米管，该碳纳米管锚固在金属-有机骨架（MOF）衍生的双金属磷化物复合材料（M16-ZIF-67-CNT-P）上，由基于16核杯芳烃的煅烧而成通过逐步热解策略将典型的ZIF-67多面体簇在一起。所获得的M16-ZIF-67-CNT-P样品具有较大的比表面积，快速的离子扩散，高的电导率和丰富的暴露的活性位点，与对照样品相比具有最高的电催化能力。同时，这种类型的纳米复合材料具有出色的阳极氧析出反应（OER）性能，在10 mA cm ^-2时需要260 mV。总体而言，MOF浸渍的簇衍生的M16-ZIF-67-CNT-P表现出高效的水分解性能。该方法可以进一步扩展到其他具有MOF材料的高核簇系统，用于能量转换和存储应用。
