（2022 Water Res）固氮研究取得新进展（图）
生物固氮 Geobacter 厌氧土壤 电化学系统
2023/3/21
福建农林大学资源与环境学院周顺桂教授团队、刘星研究员在固氮研究中取得进展。目前，工业合成氨（固氮）主要途径是Haber-Bosch工艺，其生产条件需要高温高压，既耗能又污染环境（据估计，其年均能耗约占世界能源总耗的1-2%）。而生物固氮是一种自然界广泛存在的、既经济又环境友好的固氮方式，它通过微生物代谢产生的能量，在固氮酶的作用下在常温常压下高效固定N2。研究表明，地球固氮总量的50%来自于生物固...
An electrochemical reaction that splits apart water molecules to produce oxygen is at the heart of multiple approaches aiming to produce alternative fuels for transportation. But this reaction has to ...
