The generation of ammonia from atmospheric nitrogen and water using sunlight is a preferable approach to obtaining ammonia as an energy carrier and potentially represents a new paradigm for achieving a low-carbon and sustainable-energy society. Herein, we report the selective conversion of dinitrogen into ammonia through plasmon-induced charge separation by using a strontium titanate (SrTiO3) photoelectrode loaded with gold nanoparticles (Au-NPs) and a zirconium/zirconium oxide (Zr/ZrOx ) thin film. We observed the simultaneous stoichiometric production of ammonia and oxygen from nitrogen and water under visible-light irradiation.
利用阳光将大气中的氮气和水转化为氨是一种获得氨作为能源载体的理想方法，这可能代表着实现低碳和可持续能源社会的新范例。在此，我们报告了通过使用负载金纳米粒子（Au-NPs）的钛酸锶（SrTiO3）光电极和氧化锆/氧化锆（Zr/ZrOx）薄膜进行等离子体诱导电荷分离，将氮气选择性转化为氨。我们观察到在可见光照射下，氮气和水同时按化学计量比生成氨和氧气。
