Bifunctional catalysis for water splitting is for the first time realized on Ru noble metal in the form of crystallized RuTe₂ nanoparticles on graphene. Super activity to the state-of-the-art Pt and RuO₂ is found for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) because of the high degree of crystallinity, uniform distribution of nanoparticles, and electronic effect in the catalyst system. It offers a low cell voltage of 1.57 V to drive 10 mA cm⁻², 100 mV lower than that of Pt/C-RuO₂ benchmark electrodes in an alkaline electrolyte, along with a pretty good chemical and structural stability in the strong corrosive environment. The theory calculation confirms the superior intermediates adsorption property because of the Ru/Te synergism, and Pt like/RuO₂ like character for water splitting reaction. It is a very promising catalyst in the alkaline electrolyzer due to the reliable catalytic ability and relatively low price (1/4 Pt).

首次在Ru贵金属上以在石墨烯上结晶的RuTe ₂纳米颗粒的形式实现了用于水分解的双功能催化。氢析出反应（HER）和氧析出反应（OER）具有最先进的Pt和RuO ₂活性，这是因为其结晶度高，纳米颗粒的分布均匀以及催化剂中的电子效应系统。它提供1.57 V的低电池电压以驱动10 mA cm ^-2，比Pt / C-RuO ₂低100 mV。碱性电解液中的基准电极，以及在强腐蚀性环境中相当好的化学和结构稳定性。理论计算结果证明，由于Ru / Te的协同作用以及Pt类/ RuO ₂类的特性，水分解反应具有优异的中间体吸附性能。由于其可靠的催化能力和相对较低的价格（1/4 Pt），它是碱性电解槽中非常有前途的催化剂。
