The production of ammonia from atmospheric nitrogen and water using sunlight is an important way to obtain ammonia as an energy carrier and is a new paradigm for achieving a low‐carbon and sustainable‐energy society. In this study, we attempted to enhance the ammonia photosynthesis efficiency both by increasing the electron supply using a novel photoanode composed of Au film, TiO₂, and Au‐NPs (ATA) with hybrid energy states due to modal strong coupling and by increasing the surface area of the Zr cathode. We investigated the key properties of this hybrid mode‐assisted NH₃ photosynthesis using two‐electrode systems combining photoanodes and cathodes by performing photoelectrochemical measurements and product analysis. We found that the ATA structure has high absorptivity and enhances the quantum efficiency of ammonia photosynthesis and the surface area available to adsorb N₂ on the Zr cathode is a critical factor for enhancing the reaction rate.

模态强耦合条件下对氨氮选择性固定的增强

利用阳光从大气中的氮和水生产氨是获取氨作为能源载体的重要途径，并且是实现低碳和可持续能源社会的新范例。在这项研究中，我们尝试通过使用由模态强耦合引起的具有混合能态的Au薄膜，TiO ₂和Au-NPs（ATA）组成的新型光阳极来增加电子供应，从而提高氨的光合作用效率。Zr阴极的表面积。我们研究了这种混合模式辅助NH ₃的关键特性通过执行光电化学测量和产物分析，使用结合了光阳极和阴极的两电极系统进行光合作用。我们发现ATA结构具有高吸收率并提高了氨光合作用的量子效率，并且可用于吸附Zr阴极上的N ₂的表面积是提高反应速率的关键因素。
