Today, airplanes pump a lot of climate-warming carbon dioxide into the atmosphere. But someday, carbon dioxide sucked from the atmosphere could be used to power airplanes.
现今，飞机在大气层中排放出大量的导致气候变暖的二氧化碳。但有时，大气中的二氧化碳也能够被作为飞机的燃料

A new iron-based catalyst converts carbon dioxide into jet fuel, researchers report online December 22 in Nature Communications. Unlike cars, planes can't carry batteries big enough to run on electricity from wind or solar power. But if CO2, rather than oil, were used to make jet fuel, that could reduce the air travel industry's carbon footprint — which currently makes up 12 percent of all transportation-related CO2 emissions.
12月22日，研究人员在《自然通讯》上在线报道，一种新型铁基催化剂将二氧化碳转化为喷气燃料。与汽车不同，飞机不能携带足够大的电池来依靠风能或太阳能发电。但是，如果用二氧化碳而不是石油来制造喷气燃料，这可能会减少航空业的碳足迹——目前占所有与运输有关的二氧化碳排放量的12%。

二氧化碳与氢在催化剂条件下反应生成烃和水，是烃用做航空燃料。损有余而补不足，就是热力学第二定律。
