Direct conversion of carbon dioxide and steam into hydrocarbons and oxygenates using solid acid electrolysis cells.

ABSTRACT: Electrolysis at intermediate temperatures (100-600°C) is promising because high reaction rates and high product selectivity can be achieved simultaneously during CO₂ reduction. However, intermediate temperature electrolysis has rarely been reported owing to electrolyte limitations. Here, solid acid electrolysis cells (SAECs) were adopted for electrochemically reducing CO₂. Carbon monoxide, methane, methanol, ethane, ethylene, ethanol, acetaldehyde and propylene were produced from CO₂ and steam, using Cu-containing composite cathodes at 220°C and atmospheric pressure. The results demonstrate the potential of SAECs for producing valuable chemical feedstocks. At the SAEC cathode, CO₂ was electrochemically reduced by protons and electrons. The produc
