Mechanistic and multiscale aspects of thermo-catalytic CO₂conversion to C₁products

Abstract

This review aims to catalog and summarize the advances in the experimental and theoretical approaches for CO2 activation and conversion to C1 products via heterogeneous catalytic routes.

Topotactic transformation of metal–organic frameworks to iron-based catalysts for the direct hydrogenation of CO2 to olefins

“…[1][2][3][4] Moreover, fossil energy sources are largely depleted, resulting in an increasingly tight energy supply, so for instance, the development of clean and low-carbon new energy technologies is highly required and urgent. [5][6][7] Bulk chemicals, intermediates and liquid fuels can be obtained by using hydrogen produced from hydrolysis of renewable energy sources to react with CO 2 . [8][9][10] The reaction scheme not only achieves the large-scale storage of hydrogen manufactured during the water electrolysis, but also reduces CO 2 emissions along with efficient utilization.…”

Influence of the Distance between Two Catalysts for CO2 to Dimethyl Ether Tandem Reaction

“…In recent decades, exponential development has been observed in the research focused on CO 2 capture and utilization, a major greenhouse gas [1][2][3]. Several routes have been proposed for direct and indirect conversion of CO 2 to fuels and other value-added chemicals, including hydrogenation of CO 2 to syngas, methanol (MeOH), and formic acid followed by their subsequent conversion to a variety of secondary products [4][5][6][7][8].…”

“…Calculations with thermodynamic properties reveal that lower temperatures and higher pressures shift the MeOH synthesis reaction equilibrium towards the forward direction [10]. Cu-based catalysts have been extensively studied for CO 2 to MeOH reaction, and significant progress has been made in understanding the reaction mechanism and structure-activity relation and locating the active sites [7,8,10].…”

Progress in photocatalytic CO2reduction based on single-atom catalysts

“…1 CO 2 as a typical greenhouse gas, will increase surface temperature by 1.5 to 4.5 °C for every 1-fold increase in concentration. 2 As a result of modernization, signicant CO 2 emissions have brought severe ecological and environmental problems, for instance, global warming, the greenhouse effect, glacier and permafrost melting, sea level rising, etc., 2 which are threatening the survival and living environment of human beings at all times and posing signicant obstacles to the future sustainable growth of human civilization. Countries are always paying attention to the global climate problem, and China has shown great concern and determination in this regard.…”
