A disquisition on CO2 electroreduction to C2H4: An engineering and design perspective looking beyond novel choosy catalyst materials

A comparative overview of the electrochemical valorization and incorporation of CO2in industrially relevant compounds

“…Of particular interest and high potential is the sustainable transformation of CO 2 to industrial key chemicals using renewable electricity. 53–56 The electrochemical CO 2 reduction reaction (eCO 2 RR) is a highly promising approach since a wide variety of desired products are possible, such as carbon monoxide (CO), 57–60 formic acid (HCOOH), 61–64 methanol (MeOH), 65–69 methane (CH 4 ) 70–72 and even ethylene, 73–76 ethanol (EtOH) 77–80 and other C 2+ products. 81–87 Capturing a reactive intermediate of the eCO 2 RR with a second substrate creates structural motives ubiquitous in the chemical industry, 88–90 expanding the product scope significantly and highlighting the versatility of the eCO 2 RR.…”

Tailoring Cu-Based Electrocatalysts for Enhanced Electrochemical CO2 Reduction to Alcohols: Structure–Selectivity Relationship

“…The substantial release of CO 2 into the environment has led to severe environmental deterioration due to human overdependence on fossil fuels as energy sources. − Utilization of CO 2 as a feedstock to produce value-added chemicals and carbon-based fuels, such as alcohols, hydrocarbons, and so on, offers a promising way to implement carbon neutrality. − The electrochemical CO 2 reduction reaction (CO 2 RR) enables the generation of clean and renewable energy carriers by conversion of electrical energy into chemical energy. − This is crucial for the development of sustainable energy storage and utilization systems. Nonetheless, there are still some challenging hurdles to overcome, primarily centered on achieving high selectivity in electrocatalytic CO 2 RR to produce desirable products. − In the electrocatalytic process, on the one hand, the competitive hydrogen evolution reaction needs to be suppressed, and on the other hand, carbon-based target products are obtained at low overpotentials.…”

Heterogeneous Electrocatalysis of Carbon Dioxide to Methane

“…Additionally, integrating CO 2 into the global energy cycle through hydrocarbon synthesis allows us to achieve true global carbon neutrality [8][9][10][11][12][13]. At present, the main technologies aimed at reducing CO 2 emissions include photo-, electro-, bio-, thermal, and their synergistic catalyses [14][15][16][17][18][19]. Each of these methods has its own set of advantages and limitations.…”
