A new mesoporous metal-organic framework (MOF; DUT-60) was conceptually designed in silico using Zn4 O6+ nodes, ditopic and tritopic linkers to explore the stability limits of architectures with ultrahigh porosity. The robust ith-d topology DUT-60 provides an average bulk shear modulus (4.97 GPa 0.50 GPa, respectively) for this ultra-porous framework, a key prerequisite suppress pore collapse during desolvation. Subsequently, cluster precursor approach, resulting minimal side product...

Abstract Amongst various porous materials, noble metal aerogels attract wide attention due to their concurrently featured catalytic properties and large surface areas. However, insufficient understanding investigation of key factors (e.g. reductants ligands) in the fabrication process limits on-target design, impeding material diversity available applications.
