Robust and efficient membrane contactor for carbon dioxide capture enabled by thin-film composite Janus membrane

Key Points

• Achieving enhanced gas separation, the Janus membrane effectively captures carbon dioxide from the air.
• The system shows a remarkable efficiency with carbon dioxide capture rates exceeding 90%, based on laboratory tests.
• This observational analysis evaluates the membrane contactor's performance under varying operational conditions.
• Supporting carbon neutrality efforts, this method offers a viable solution to reduce atmospheric carbon dioxide levels.
