Electrochemical Carbon Deposition from CO 2 in Molten Carbonates: Substrate-Dependent Growth

Key Points

• The aim is to investigate how substrate selection influences the electrochemical deposition of carbon from molten carbonates.
• Systematic examination of carbon formation using inert electrodes.
• Electrochemical processes assessed at various cathodic potentials.
• Observation of deposition transition within a set time frame.
• Carbon deposition initiated within 30 minutes at optimal cathodic potentials.
• Different substrates lead to varied growth patterns of deposited carbon.
• No additional catalysts were needed for the carbon formation process.
