A mini review on chemical fixation of CO2: Absorption and catalytic conversion into cyclic carbonates

Abstract

In this article, we present our research results on chemical fixation of CO 2 using organobismuth compounds. We fabricated bismuth biphenoate complex, Zn-Mg-Al composite oxides, and SBA-15 or Al-SBA-15 immobilized hydroxyl ionic liquid for CO 2 cycloaddition onto epoxides. The hypervalent bismuth compounds show good ability for association and dissociation with CO 2 . The bismuth biphenolate complexes are catalytically effective for the cycloaddition reaction. The heterogeneous catalysts, viz. Zn-Mg-Al oxides and SBA-15 or Al-SBA-15 immobilized ionic liquid, are efficient for the synthesis of cyclic carbonate from CO 2 and epoxide. It is found that the presence of a trace amount of water can improve the catalytic activity of the immobilized ionic liquid.

Conversion of Methane and Carbon Dioxide to Higher Value Products

“…The generation of energy used for CO 2 transformation, if based on hydrocarbon raw materials, ironically still produces large amounts of CO 2 . In addition the resulting organic chemicals in which CO 2 is incorporated as the result of these transformations release CO 2 at the end of their use . However, despite the fact that, currently, the usage of CO 2 in the chemical industry cannot reduce significantly the global CO 2 levels, it is believed that the full potential of the fixation of CO 2 into value added products has not yet been completely explored.…”

“…The direct use of non-hydrocarbon based energy sources for reduction of CO 2 would change the above perspective and allow recycling of carbon dioxide via chemicals and liquid fuels. Thus, the further development of industrial processes that are utilizing CO 2 for high-demand products is of importance. , …”

Non-isocyanate polyurethane/epoxy hybrid materials with different and controlled architectures prepared from a CO2-sourced monomer and epoxy via an environmentally-friendly route

“…The cyclic carbonate can be used for various purposes, such as aprotic polar solvents, fuel additives, electrolytes and intermediates for polymer synthesis. 5,6 And many researchers have devoted effort to the synthesis of cyclic carbonates, such as Chen et al 7 In recent years, the utilization of 5CC acting as CO 2 -sourced monomer to produce polyurethane (the so-called nonisocyanate polyurethane (NIPU)) has attracted considerable attention due to avoiding the use of toxic feedstock during the preparation process. It is well known that the traditional polyurethane (PU) is usually synthesized from toxic isocyanate and polyol.…”

Novel carbonyl iron–bismuth clusters – synthesis, structure, CO2 insertion and potential as molecular precursors for BiFeO3

“…Noteworthy, the first examples of CO 2 fixation by organometallic bismuth compounds to give carbonates were reported only recently by Breunig et al and Yin et al [28,29]. Currently there is some interest in bismuth-containing catalysts for cycloaddition of CO 2 to epoxides [30]. However, due to its low stability we were not able to study the reversibility of CO 2 fixation or the catalytic properties of the heterobimetallic alkoxido cluster 3.…”
