The team used semiconductor catalysts to turn carbon dioxide and water into oxygen and ethylene, a hydrocarbon commonly used to produce spacecraft propellants, according to the SCMP.
“This technology mimics the natural photosynthesis process of green plants through engineered physical and chemical methods, utilizing carbon dioxide resources in confined spaces or extraterrestrial atmospheres to produce oxygen and carbon-based fuels,”
