科学家发现一种利用空气发电的酶

2023-03-11 21:14:00 by 最后的守护者

根据发表在《自然》期刊上的一项研究,澳大利亚科学家发现了一种能利用空气中微量氢发电的酶。研究人员从名叫耻垢分枝杆菌(Mycobacterium smegmatis)的细菌中提取出负责利用空气中氢气的酶。名叫 Huc 的酶能将氢气转变成电流。Huc 的转换效率非常高,我们所呼吸的大气中氢气浓度只有 0.00005%,而 Huc 甚至能在低于这个浓度下消耗氢气。研究人员还发现,Huc 具有强有力的稳定性,可以冷冻起来,加热到 80 摄氏度,它仍然能维持其功能。这项研究目前处于早期阶段,它有可能成为小型飞行器使用的太阳能动力的替代。
