We present the fabrication of a novel Starfruit‐shaped metal‐organic framework (SMOF) composed of zirconium and Tetra(4‐carboxyphenyl)porphine linkers. The SMOF exhibits a unique morphology with edge‐sharing two‐dimensional (2D) nanosheet petals. Our investigation unravels a captivating transformation process, wherein three‐dimensional (3D) shuttle‐shaped MOFs form initially and subsequently evolve into 2D nanosheet‐based SMOF structures. The distinct morphology of SMOF showcases superior catalytic activity in detoxifying G‐type nerve agent and blister agent simulants, surpassing that of its 3D counterparts. This discovery of the 3D‐to‐2D transition growth pathway unlocks exciting opportunities for exploring novel strategies in advanced MOF nanostructure development, not only for catalysis but also for various other applications. Starfruit‐shaped Zirconium metal‐organic frameworks (SMOF), with edge‐sharing two‐dimensional (2D) nanosheet petals, can form spontaneously from the transformation of three‐dimensional (3D) MOF crystals in a solvothermal synthesis. The distinct morphology of SMOF showcases superior catalytic activity in detoxifying G‐type nerve agent and blister agent simulants, surpassing that of its 3D counterparts.
