We propose connected Ir nanoparticle catalysts (Ir/SiO) by coating 1.8 nm Ir particles with high density onto silica for the oxygen evolution reaction. Nanoparticles form electron-conducting networks, which can eliminate the need for an electron-conducting support. Ir/SiO showed a high electrochemical surface area, mass activity, and water electrolysis performance.
我们提出通过在二氧化硅上高密度包覆1.8纳米铱颗粒来制备用于析氧反应的连接型铱纳米颗粒催化剂（Ir/SiO）。纳米颗粒形成电子传导网络，这可以消除对电子传导载体的需求。Ir/SiO表现出高的电化学表面积、质量活性和水电解性能。
