Nanomaterials and processes for carbon capture and conversion into useful by‐products for a sustainable energy future

Abstract

This review provides a comprehensive reflection of the recent advances in nanomaterials and processes for carbon dioxide (CO2) capture and conversion. It is divided into two sections: carbon capture, and conversion into useful by‐products. The latest developments in nanotechnology‐enabled carbon capture processes along with an overview of the conventional technologies for carbon capture are described. Descriptions of by‐product conversion include conversion into important chemicals, liquid fuels, and hydrocarbon such as carbonate, methane, methanol, and formic acid. Finally, perspectives on the future directions in carbon capture and storage technology are presented. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd

Functionalization of POSS nanoparticles and fabrication of block copolymer nanocomposite membranes for CO2 separation

“…The diffusion and solubility coefficients of CO 2 were determined using Eqs. (2) and (1) and the dimethylsilyl spacer between the cage structure of POSS and PEG ligand both leads to higher CO 2 diffusion coefficient through the nanocomposite membranes which in turn increases the CO 2 permeability. Therefore, the nanofillers containing the THF complex and the dimethylsilyl spacer increase the mobility of the polyether segment more than the nanofillers which do not have such moiety.…”

“…A diverse number of materials and methods are under study for capture, storage and conversion of CO 2 to mitigate the global warming. The emerging and already established concepts for CO 2 capture encounter the challenge of finding an economically feasible and efficient separation technology from effluent gas streams [1,2]. Low energy requirements and cost effectiveness of membrane gas separation processes have made this technology an ideal candidate in this quest.…”

Heterogeneous catalysts for the hydrogenation of amine/alkali hydroxide solvent captured CO2 to formate: A review

“…Carbon capture and utilization (CCU) can serve as an alternative process to CCS, where the captured CO 2 can be utilized as renewable and abundant carbon feedstock to manufacture fuels and value-added chemical products. 22,[31][32][33] The valorization of CO 2 is likely to compensate part of the energy penalty caused by the PCC process, which is favorable to the implication of the large-scale PCC process. 34 In the presence of a suitable catalyst, CO 2 can be transformed into a wide variety of valuable products, including methanol, formic acid (FA), carbon monoxide, and hydrocarbons.…”

CO2 Separation in Nanocomposite Membranes by the Addition of Amidine and Lactamide Functionalized POSS® Nanoparticles into a PVA Layer

“…Various materials and methods are being developed for capture and storage, and in some cases, conversion, to mitigate the effect of global warming. Emerging and already established concepts for CO 2 capture encounter the challenge of finding an economically feasible and efficient separation technology from effluent gas streams [ 8 , 9 ]. The study of advanced materials and modern manufacturing methods have helped to obtain new and improved membranes that have better separation performances, thus contributing to obtain environmental friendly gas membrane separation processes which demand less energy.…”
