Conversion of CO2 to defective porous carbons in one electro-redox cycle for boosting electrocatalytic H2O2 production

Enhanced Selectivity in the Electroproduction of H2O2 via F/S Dual‐Doping in Metal‐Free Nanofibers

“…Figure 3g and Table S3, Supporting Information, summarize the performance of FS-CFs 7:3 catalyst against the current state-of-the-art (details in Table S3, Supporting Information). [11,18,21,25,31,34,36] Some works (Figure 3g blue area) report the highest selectivity value possible, [37][38][39][40][41] typically within the partial current density range of 0.5 mA cm −2 . Others present the selectivity around the peak H 2 O 2 partial current density.…”

Overall Carbon‐neutral Electrochemical Reduction of CO2 in Molten Salts using a Liquid Metal Sn Cathode

“…Electrochemical reduction of CO 2 in aqueous solutions is limited by competitive hydrogen evolution and the low solubility of CO 2 [1–3] . However, it has been recently demonstrated that molten salt can function as an ideal electrolyte to capture, activate and convert CO 2 into advanced carbon and hydrocarbon [4–8] . This is due to a thermodynamically spontaneous reaction between CO 2 and O 2− in molten salts (Figure S1, Supporting Information), which thereby increases the solubility of CO 2 in molten salts to several moles per liter [9–12] .…”

Pure and Metal‐confining Carbon Nanotubes through Electrochemical Reduction of Carbon Dioxide in Ca‐based Molten Salts

“…Using excess capacity of electrolytic aluminum industry to electrolyze industrial CO 2 emission can not only reduce carbon emission but also relieve the pressure of production regulations. A thermodynamically spontaneous dissolution/absorption of CO 2 into molten carbonate in Li 2 O‐containing molten salts (Figure S1, Supporting Information) is the key‐enabling factor to achieve high current efficiency ( CE ) [10–13] . Based on industrial maturation of molten salt electrolysis and promising functionality of CO 2 ‐derived materials, solar‐driven molten salt electrochemical CO 2 reduction is an attractive artificial photosynthesis [14–16] .…”

“…A thermodynamically spontaneous dissolution/ absorption of CO 2 into molten carbonate in Li 2 O-containing molten salts (Figure S1, Supporting Information) is the keyenabling factor to achieve high current efficiency (CE). [10][11][12][13] Based on industrial maturation of molten salt electrolysis and promising functionality of CO 2 -derived materials, solardriven molten salt electrochemical CO 2 reduction is an attractive artificial photosynthesis. [14][15][16] Such a protocol, however, is hampered by the surging lithium resource price along with the booming lithium-ion battery industry.…”
