Abstract：CO2 reduction is an important part of the international space station CO2 treatment.CO2 reduction technology can not only remove the CO2 generated by human metabolism process,but also be combined with electrolyzed water technology together to achieve oxygen regeneration.CO2 reduction technology used in space station includes Sabatier,Bosch,CO2 electrolysis and CO2 pyrolysis.After thirty years of theoretical and experimental research,Sabatier reduction was ultimately identified as the CO2 reduction method in the International Space Station.However,because of its low closure,Sabatier method is difficult to be applied in even longer manned space missions such as the deep space exploration.Other methods that can accomplish complete close reduction may take the place of Sabatier method after their maturity and become superior reduction technologies.
