Building up a lunar settlement is the ultimate aim of lunar exploitation. Yet, limited fuel and oxygen supplies restrict human survival on the Moon. Herein, we demonstrate the resource utilization of lunar soil for extraterrestrial fuel and oxygen production, which may power up our solely natural satellite and supply respiratory gas. Specifically, the lunar soil is loaded with Cu species and employed for electrocatalytic CO conversion, demonstrating significant production of methane. In addition, the selected component in lunar soil (i.e. MgSiO) loaded with Cu can reach a CH Faradaic efficiency of 72.05% with a CH production rate of 0.8 mL/min at 600 mA/cm. Simultaneously, an O production rate of 2.3 mL/min can be achieved. Furthermore, we demonstrate that our developed process starting from catalyst preparation to electrocatalytic CO conversion is so accessible that it can be operated in an unmmaned manner via a robotic system. Such a highly efficient extraterrestrial fuel and oxygen production system is expected to push forward the development of mankind's civilization toward an extraterrestrial settlement.
建立月球定居点是月球开发的最终目标。然而，有限的燃料和氧气供应限制了人类在月球上的生存。在此，我们展示了利用月球土壤生产外星燃料和氧气的资源利用方式，这可能为我们唯一的天然卫星提供动力并供应呼吸气体。具体而言，月球土壤负载铜物种并用于电催化CO转化，显示出大量甲烷的产生。此外，负载铜的月球土壤中选定成分（即MgSiO）在600 mA/cm² 时，CH₄ 法拉第效率可达72.05%，CH₄ 产率为0.8 mL/min。同时，O₂ 产率可达2.3 mL/min。此外，我们证明了我们开发的从催化剂制备到电催化CO转化的过程非常易于操作，可以通过机器人系统以无人方式运行。这样一个高效的外星燃料和氧气生产系统有望推动人类文明向地外定居点发展。
