Understanding the complexity in bridging thermal and electrocatalytic methanation of CO₂

Abstract

This review provides clues to understanding the complexity of moving from thermal to electrocatalysis and the tools for designing next-generation electrocatalysts for CO2 reduction to methane.

Ionic Liquid-Functionalized Metal–Organic Frameworks/Covalent–Organic Frameworks for CO2 Capture and Conversion

“…Light olefins (C 2 –C 4 ) and alkanes (methane, CH 4 , for example) are other groups of building blocks derived from CO 2 , and the conversion processes have been generally investigated through different catalytic routes. Liu et al gave a tutorial review on the thermocatalytic multistep and direct electro-/photoelectron catalytic technologies for CO 2 methanation . The Cu-based MOFs (Cu-MOF-74, Cu 2 O-Cu MOF, and Cu-ade MOF) were used for the electrocatalytic conversion of CO 2 to CH 4 .…”

From Plastic Waste to Treasure: Selective Upcycling through Catalytic Technologies

“…Thermocatalytic conversion primarily involves overcoming the thermodynamic energy barrier in a catalytic reaction system via heating, thereby promoting the conversion of reactants to products. [33] Therefore, it is essential to consider the deconstruction and upcycling of plastics from thermodynamic and kinetic perspectives. As depicted in Figure 4, the selective conversion of polymers to the desired products involves a certain reaction barrier (E a ) and an enthalpy difference (ΔH rxn ) between the reactants and products.…”

Tuning the selectivity of the CO2 hydrogenation reaction using boron-doped cobalt-based catalysts

“…[1][2][3][4] This is because carbon dioxide functions as a chemical raw material in this process, producing renewable chemicals without using fossil fuels. [5][6][7] The hydrogenation of CO 2 usually produces C 1 compounds, such as CO, CH 4 , and CH 3 OH. [8][9][10][11] Among C 1 products, CO is a resource for the synthesis of alcohols, liquid hydrocarbons, and organic acids using existing syngas conversion infrastructure.…”
