Several measures, including crude oil recovery improvement and carbon dioxide (CO2) conversion into valuable chemicals, have been considered to decrease the greenhouse effect ensure a sustainable low-carbon future. The Knoevenagel condensation CO2 fixation introduced as two principal solutions these challenges. In present study for first time, bio-metal–organic frameworks (MOF)(Cu)/graphene oxide (GO) nanocomposites used catalytic agents reactions. view of attendance amine groups, biological MOFs with NH2 functional groups Lewis base sites protruding on channels' internal surface were used. bio-MOF(Cu)/20%GO performs efficaciously in fixation, leading more than 99.9% TON = 525 via solvent-free reaction under 1 bar atmosphere. It has shown that are highly due basic sites, i.e., NH2, pyrimidine, C═O groups. Besides, active exert synergistic effects render bio-MOF(Cu)/10%GO nanostructures efficient catalysts, significantly accelerating reactions aldehydes malononitrile substrates, thanks high TOF (1327 h–1) acceptable reusability. Bio-MOFs can be stabilized using GO oxygen-containing contribute substitutes, an expeditious speed facilitating substrate absorption.

In this study, we synthesized and characterized a series of cobalt(II) complexes bearing linear tetradentate N4 ligands. These Co(II)-N4 proved to be efficient catalysts for the cycloaddition reaction between carbon dioxide epoxides even at room temperature 1 bar pressure without need solvents or cocatalysts. Furthermore, when combined with (triphenylphosphoranylidene)ammonium chloride (PPNCl) as cocatalyst, Co-N4 exhibited an impressive turnover frequency up 41,000 h

Abstract Developing highly efficient nonprecious heterogeneous catalysts for the cycloaddition of carbon dioxide (CO 2 ) to cyclic carbonates is crucial but challenging in modern chemical industry. Here, a facile and scalable molecules‐confined pyrolysis approach demonstrated synthesis nitrogen‐coordinated transition‐metal (TM) single‐atom (SACs). Moreover, various coordination structures metal centers forms nitrogen species are successfully revealed. The designed TM SACs show excellent catalytic performance CO with epoxides under solvent‐free mild conditions. Among them, optimum Zn SAC 13.2 wt.% content achieves >99% yield at 80 °C within h propylene oxide carbonate. comprehension relationship between reaction mechanism over adjacent N further enhanced through experimental investigations theoretical simulations. Significantly, high density Lewis acid–base sites (Zn species) can appropriately regulate activation epoxide energy cycloaddition, respectively, thus improving performance. This work provides new insight into design active stable reactions.
