非晶質 RuO_{2} ナノ粒子は0.1 M硫酸中での酸素発生反応（OER）に対して高い電極触媒活性を示すが、電極触媒反応中の耐久性は低い。一方、高結晶性 RuO_{2} ナノ粒子は、高い OER 活性だけでなく高い耐久性も示すことがわかった。

Amorphous RuO_{2} nanoparticles have high electrocatalytic activity for oxygen evolution reaction (OER) in 0.1M H_{2}SO_{4} but are unstable during the electrocatalytic reaction. RuO_{2} nanoparticles with high crystallinity simultaneously achieve high OER activity and stability.
