Special Issue Information

Dear Colleagues,

Catalytic CO2 conversion is a promising route to reducing CO2 emission and providing valuable chemicals and fuels. However, the traditional CO2 conversion process usually suffers from high reaction temperature and large energy consumption.  To achieve a carbon-neutral CO2 conversion process, it is necessary to drive CO2 conversion by using renewable energies such as solar energy, wind, and/or renewable hydrogen and electricity. Therefore, CO2 catalytic conversion including photocatalysis, electrocatalysis, and thermalcatalysis has attracted wide attention and will play a more important role in the near future. This Special Issue welcomes both review and original research articles on all aspects of catalytic CO2  conversion.

This Special Issue will focus on, but is not limited to:

  • Development of novel catalysts with high efficiency, electivity, and stability;
  • Novel catalytic CO2 conversion pathways and technologies;
  • Mechanistic and kinetic understanding of CO2 catalytic conversion;
  • Design and development of novel reactors for photocatalysis, electrocatalysis, thermalcatalysis, etc.;
  • Integrated approaches combining CO2 capture, conversion , production separation , and/or reactant recycling;
  • Technical-economic analysis of technologies for catalytic CO2

Electrocatalytic CO2-reduction technology can convert CO2 into methanol and other chemicals using renewable electricity, but the techno-economic prospects of the large-scale electrocatalytic reduction in CO2 into methanol are not clear. This paper conducted sensitivity analysis to confirm the key parameters affecting the cost of methanol production from an alkaline flow cell and a neutral MEA electrolyzer, compared the cost of the two electrolyzers under laboratory data and optimized data scenarios, and analyzed the key parameter requirements of the two electrocatalytic systems to achieve profitable methanol production. The results show that electricity price, Faradaic efficiency, cell voltage, and crossover/carbonate formation ratio are the most sensitive parameters affecting the cost of methanol production. The alkaline flow cell had higher energy efficiency than the MEA cell, but the saving cost of electricity and the eletrolyzer cannot cover the cost of the regeneration of the electrolyte and CO2 lost to carbonate/bicarbonate, resulting in higher methanol production costs than the MEA cell. When the crossover/carbonate formation ratio is zero, the cost of methanol production in an alkaline flow cell and a neutral MEA cell can reach under 400 USD/tonne in the cases of energy efficiency more than 70% and 50%, respectively. Therefore, enhancing energy efficiency and ensuring a low crossover/carbonate formation ratio is important for improving the economy of electrocatalytic methanol production from CO2 reduction. Finally, suggestions on the development of electrocatalytic CO2 reduction into methanol in the future were proposed. Full article
