Summary: | 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.
NH3 sees the light of day: A highly selective and visible‐light‐responsive plasmonic NH3 synthesis device containing a Au nanostructure and a Zr/ZrOx thin film was developed. N2 gas was reduced to NH3 by using water as an electron donor through plasmon‐induced charge separation under visible light irradiation. |
