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. Global warming causes abnormal climates around the world, threatening the survival of the human race. Reducing greenhouse gases is crucial to solving the increasingly concerning problem of global warming, which requires converting atmospheric carbon dioxide into other substances. ....
