Cobalt-based MOF nanoribbons with abundant O/N species for cycloaddition of carbon dioxide to epoxides

2D Co-Based Metal–Organic Framework Nanosheets for the One-Pot Synthesis of Cyclic Carbonates from Olefins and CO2

“…The O 1s spectra could be deconvoluted into two peaks corresponding to Co−O (531.8 eV) and C−O (533.5 eV), respectively, as shown in Figure 2c. 36 Moreover, the Co 2p spectra of two samples displayed distinct peaks appearing at 781.3 and 797.5 eV, which were assigned to Co 2p 3/2 and Co 2p 1/2 , respectively, along with two satellite peaks at 786.2 and 803.1 eV (Figure 2d), which indicated that Co ions in both samples existed in the form of Co 2+ . Notably, the dimension-reduction strategy did not significantly change the coordination environment in the MOF samples.…”

Optimization and kinetics of crown ether-based hydroxyl-rich organic polymers for sustainable CO2 fixation and iodine vapor adsorption

“…17,18 While the high free energy of epoxides can counterbalance the high thermal stability of CO 2 in the atmosphere, certain catalysts make the xation of CO 2 onto epoxides thermodynamically advantageous. The current state of the art involves the development of a wide range of catalysts such as ionic liquids (ILs), [19][20][21] metal complexes, [22][23][24][25][26][27] metal organic frameworks (MOFs), [28][29][30][31][32] supported catalysts, [33][34][35][36][37] covalent organic frameworks (COFs), [38][39][40] and porous organic polymers (POPs), [41][42][43][44][45][46][47] each possessing distinct structures and functions, to efficiently facilitate this reaction. Among these, POPs exhibit unique CO 2 conversion and I 2 capture properties, due to their high intrinsic specic surface area, controllable pore size, synthetic versatility, exceptional physicochemical stability, and facile functionalization for creating metal-active centers.…”

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

“…This advancement has garnered significant attention from researchers in the field. By eliminating halide ions during the reaction process, environmental pollution is effectively mitigated, and the resulting cyclic carbonates require less complex purification procedures. , Liu and colleagues designed and synthesized two melamine-based organic polymers, UM-OP and AM-OP, and investigated their catalytic performance in the ring-opening reaction under conditions of no halogen, no solvent, and no cocatalyst. Experimental results showed that the UM-OP catalyst exhibited higher catalytic activity .…”
