Encapsulation of an Ionic Metalloporphyrin into a Zeolite Imidazolate Framework in situ for CO₂ Chemical Transformation via Host–Guest Synergistic Catalysis

It is a great challenge to rationally integrate multiple reactive sites into a composite material with confined nanospace, which can be applied as a nanoreactor to facilitate targeting catalytic reaction. In this work, an ionic metalloporphyrin has been encapsulated in situ into ZIF-8 for a solvent-free synthesis of cyclic carbonates from CO₂ and epoxides without any co-catalyst under 1 atm CO₂ .
