Nitrogen-rich metal-organic framework of nickel(ii) as a highly efficient and reusable catalyst for the synthesis of cyclic carbonates at ambient pressure of CO₂.

ABSTRACT: Nitrogen-rich metal organic frameworks (MOFs) structures have a great potential for the chemical fixation of CO₂. In this direction, we have utilized the highly efficient nitrogen-rich dual linker MOF of nickel(ii) as a heterogeneous catalyst in solvent-free chemical fixation of CO₂ into cyclic carbonates at ambient pressure. In this present work, nitrogen-rich nickel-MOF, Ni-ImzAdn, was synthesized from imidazole and adenine as efficient nitrogen-rich linkers under hydrothermal conditions (Imz = Imidazole and Adn = Adenine). The Ni-ImzAdn was characterized thoroughly via various physicochemical analyses such as FT-IR, SEM, EDX, EDX-mapping, XRD, ICP-OES, BET, BJH, TG-DTA, CO₂-TPD, and NH₃-TPD. Ni-ImzAdn with adequate free nitrogen sites e
