A research team have developed a high-efficiency photocatalyst that converts carbon dioxide (CO2), a major contributor to climate change, into natural gas (methane, CH4). The team is led by Professor In Soo-il of the Department of Energy Science & Engineering at DGIST. The study is published in the journal Applied Catalysis B: Environment and Energy.
