Biomimetic assembly to superplastic metal-organic framework aerogels for hydrogen evolution from seawater electrolysis.

ABSTRACT: Applications for metal-organic frameworks (MOFs) demand their assembly into three-dimensional (3D) macroscopic architectures. The capability of sustaining structural integrity with considerable deformation is important to allow a monolithic material to work reliably. Nevertheless, it remains a significant challenge to introduce superplasticity in 3D MOF networks. Here, we report a general procedure for synthesizing 3D superplastic MOF aerogels inspired by the hierarchical architecture of natural corks. The resultant MOFs exhibited excellent superplasticity that can recover fully and rapidly to its original dimension after 50% strain compression and unloading for >2000 cycles. The 3D superplastic architecture is achieved by successively assembling one-dimensional (1D) to two-dimensional (2D
