Melamine-based nitrogen-heterocyclic polymer networks as efficient platforms for CO2 adsorption and conversion

Aniline-Based Hyper-Cross-Linked Polymer–In2O3 Composite Boosting CO2 Epoxide Ring-Opening Reaction Activity without Cocatalysts

“…This provides reference and assistance for the development of catalysts with hydrogen bond donor groups to achieve ring-opening reactions under conditions of no halogen, no solvent, and no cocatalyst. 30 The surfaces of metal oxide catalysts are rich in metal cations and oxygen anions, serving as Lewis acid and Lewis amine base sites, respectively. This enables the formation of frustrated Lewis pairs, facilitating the effective activation of CO 2 through Lewis acid−base interactions, leading to catalytic enhancement.…”

“…Among them, the PAN-IM catalyst containing an imidazole ring demonstrated effective catalysis of the ring-opening reaction under conditions of no halogen, no solvent, and no cocatalyst.
