The efficient and selective conversion of CO<sub>2</sub>as a sustainable C<sub>1</sub>resource into valuable chemicals energy-related products through catalysis is reviewed.
Carbon dioxide chemistry (in particular, capture and conversion) has attracted much attention from the scientific community due to global warming associated with positive carbon accumulation. The most widely used chemical absorption technique for storage/sequestration (CCS) would be essentially adopting amino-containing absorbents through formation of C–N bond in terms mechanistic consideration. However, extensive energy input desorption compression process a crucial barrier realize...
Ionic liquids (ILs), a kind of novel green medium composed entirely cations and anions, have attracted considerable attention due to their unique properties such as non-volatility, tunable polarity, high stability so on. In this article, the latest progress on absorption subsequent conversion CO2 by using ILs absorbents, catalysts or promoters will be summarized. The chemical performance ILs, especially task-specific ionic (TSILs) amino-functionalized superbase-derived protic has been...

Furthermore, the catalyst could be recycled over five times appreciable loss catalytic activity. The effects structure...
Carbon dioxide, a greenhouse gas mainly from the consumption of fossil fuel, is regarded as an attractive feedstock in view synthetic chemistry. Great efforts have been devoted to developing catalytic processes for converting CO2 into value-added compounds with reduced carbon footprint. Among versatile applications organic synthesis, can serve promising raw material fuel production, especially methanol. 'Coming and returning fuel' appealing objective terms sustainable development associated...
Steric bulk controls CO2 absorption: N-substituted amino acid salts in poly(ethylene glycol) reversibly absorb nearly 1:1 stoichiometry. Carbamic is thought to be the absorbed form of CO2; this was supported by NMR and situ IR spectroscopy, DFT calculations. The captured could converted directly into oxazolidinones thus desorption sidestepped.

To address the CO2 accumulation in atmosphere, various initiatives have been proposed, among which capture and utilization (CCU) is regarded as an appealing strategy to reconcile carbon emission resource utilization. Especially, integrated (ICCU), i.e. performing in-situ conversion can circumvent energy-intensive desorption step thus facilitate establishing step- energy-efficient process, rendering at mild conditions particularly low pressure due substantial activation upon uptake. However,...
