A research team led by Professor Jungki Ryu of UNIST, in collaboration with other universities, has developed a copper-based catalyst that can efficiently convert CO₂ into high-purity methanol, a crucial step in reducing greenhouse gas emissions and promoting sustainable energy sources. Methanol, a versatile chemical used in various industries, is considered a promising hydrogen carrier and fuel cell energy source due to its easy storage and transport properties. The team's innovative catalyst achieved a remarkable 70% selectivity in methanol production, outperforming traditional copper catalysts. By integrating nanoscale copper particles with copper pyrophosphate, the catalyst suppresses unwanted byproducts like hydrogen, simplifying the purification process. The fabrication method, inspired by lithium-ion battery technology, allows for cost-effective production and easy scalability. Additionally, the catalyst follows a unique synthesis pathway starting from formic acid, offering new insights for future catalyst development. Professor Ryu highlighted the catalyst's potential for industrial-scale carbon resource conversion and emphasized plans for further technology expansion and commercial deployment.
