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.
Researchers develop photocatalyst with irregular surface characteristics to convert carbon dioxide into fuel). The team is led by Professor In Soo-il of the Department of Energy Science & Engineering at DGIST. The study isis crucial to solving the increasingly concerning problem of global warming, which requires converting atmospheric carbon dioxide into other substances.using only solar energy and water.
Previously, crystalline titanium dioxide, which has a periodic lattice structure, was analyzed as a photocatalytic material. However, the formation of active sites for the trivalent cations of titanium maintained a methane-conversion performance of 99.3% for the first 6 hours after 18 hours of photoreaction, making it 4.22 times more regenerative than the crystalline photocatalyst retrieved 3 June 2024 from https://phys.org/news/2024-06-photocatalyst-irregular-surface-characteristics-carbon.
