The establishment of stable cycling CO2 and O2 is essential for Environmental Control Life Support Systems (ECLSS) in extraterrestrial environments, particularly long-duration missions aboard Space Stations future Martian bases. development CO2-to-O2 technologies demonstrating superior oxygen recovery rates, enhanced conversion efficiency, optimized energy efficiency critical achieving closed-loop material regeneration. This review systematically examines technological status conversion, categorizing emerging approaches into two frameworks: “two-step generation” “one-step generation”. Two-step generation includes thermal catalytic hydrogenation reduction electrolysis water production, which are primarily utilized Station; one-step encompasses electrocatalytic plasma predominantly employed environments. Through comparative analysis underlying principles operational characteristics, we identify three challenges impeding maturation: (1) deactivation materials, the formation carbon deposits, inadequacy mechanisms; (2) description transformation process unclear, making it challenging to regulate conversion. Additionally, suppressing side reactions proves be difficult; (3) degree recycling a single substance relatively low. effective, efficient, stable, reliable technology will provide solid foundation reducing launch costs ensuring sustainable human habitation
