Although ruthenium oxide nanoparticles (RuO₂), graphene, and their composites have been widely used as supercapacitor electrode materials, transparent supercapacitors of these materials have been rarely investigated. In this work, we fabricated high-performance transparent solid-state supercapacitors of 2 nm RuO₂ decorated on a 3D nitrogen-doped reduced graphene oxide aerogel (NGA) with 27–54% transparency. The as-fabricated symmetric supercapacitor of RuO₂/NGA at a finely tuned mass loading of 16.3 μg cm⁻² with a finely tuned transmittance of 34.1% at a wavelength of 550 nm exhibits a maximum areal energy of 0.074 μW h cm⁻² and a maximum areal power of 64 μW cm⁻². The cycling stability of the device can also be maintained at 100% over 2000 cycles. The high transparent supercapacitor in this work may practically be used in many advanced transparent electrical devices.

在3D氮掺杂石墨烯气凝胶上装饰的2 nm氧化钌纳米颗粒的透明超级电容器†

尽管氧化钌纳米颗粒（RuO ₂），石墨烯及其复合物已被广泛用作超级电容器电极材料，但很少研究这些材料的透明超级电容器。在这项工作中，我们制作了2 nm RuO ₂的高性能透明固态超级电容器，该电容器在3D氮掺杂的还原氧化石墨烯气凝胶（NGA）上装饰，透明度为27％至54％。精细制备的RuO ₂ / NGA对称超级电容器的质量载荷为16.3μgcm ^-2，在550 nm波长处的精细透射率为34.1％，其最大面能量为0.074μWh cm ^-2，并且最大面功率为64μWcm ^-2。在2000次循环中，设备的循环稳定性也可以保持在100％。这项工作中的高透明超级电容器实际上可以用于许多先进的透明电气设备中。
