CO₂ Catalysis

Abstract

Out of thin air: In this Editorial, the Guest Editors introduce a Special Issue on Carbon Dioxide Conversion Catalysis, discuss its importance in modern chemical processes, and highlight a few examples of its use in industry, such as the synthesis of cyclic carbonates and the conversion of CO2 into fuels.

Hydrogen‐assisted Carbon Dioxide Thermochemical Reduction on La0.9Ca0.1FeO3−δ Membranes: A Kinetics Study

“…Capturing and utilizing CO 2 has both environmental and economic benefits . As CO 2 is an abundant and cheap C 1 feedstock for industry applications, upgrading CO 2 to value‐added chemicals such as CO, CH 3 OH, and CH 4 is an essential step towards a low‐carbon economy. Recently, CO 2 thermal reduction into CO and O 2 was achieved in a ceria membrane reactor at 1500 °C .…”

“…[1] Capturing and utilizingC O 2 has both environmental and economic benefits. [2][3][4][5] As CO 2 is an abundant andc heap C 1 feedstock for industry applications, [3,6] upgrading CO 2 to value-added chemicals such as CO, [7][8][9] CH 3 OH, [10] and CH 4 [11,12] is an essential step towardsalow-carbon economy.R ecently,C O 2 thermalr eduction into CO and O 2 was achieved in ac eria membrane reactor at 1500 8C. [13] Herein, we focus on af uel-assisted CO 2 thermochemicalr eduction process on an oxygen-permeable membrane (OPM), which operates within al ower temperature range of 850-1030 8C.…”

Role of Iron on the Structure and Stability of Ni3.2Fe/Al2O3 during Dynamic CO2 Methanation for P2X Applications

“…Within the "powerto-gas" process chain, excess renewable electric power is catalytically converted to methane, a chemical energy carrier (Sabatier reaction, [Equation (1)]). [4] Renewable H 2 from electrochemical water splitting, [5] and CO 2 , e. g. from biomass gasification or industrial exhaust gases, [6] can be used as reactants for this catalytic process. The production of hydrogen via electrolysis in a renewable energy scenario depends directly on weather-related fluctuations, especially when produced in decentralized plants with small H 2buffer tanks.…”

New Coordination Complexes Based on the 2,6-bis[1-(Phenylimino)ethyl] Pyridine Ligand: Effective Catalysts for the Synthesis of Propylene Carbonates from Carbon Dioxide and Epoxides

“…The chemical fixation and conversion of carbon dioxide into valuable chemicals is generally regarded as an excellent method from both the environmental protection and resource utilization standpoints [1,2,3,4,5]. As a naturally abundant, cheap, recyclable, and nontoxic carbon source, carbon dioxide has been involved in various organic reactions, especially the cycloaddition of epoxides with carbon dioxide to produce carbonates [6,7,8,9,10,11]. This reaction is a standard “atom-economy” and “green-chemistry” reaction to produce environmentally-friendly propylene carbonate that is widely utilized as a special solvent in many chemical industries such as liquefied natural gas (LNG), the textile printing industry, lithium batteries, and wood processing [12,13,14,15].…”
