The lattice strain of IrO plays a critical role in determining its OER activity. The Ir-O bond length change in IrO coordination induces lattice strain. Increasing the annealing temperature results in a stretching strain along the c axis and a compressive strain on the a and b axes, leading to a larger c/a ratio. Enhancing the lattice strain decreases the c/a ratio, which is beneficial for improving OER activity.
氧化铱（IrO）的晶格应变在决定其析氧反应（OER）活性方面起着关键作用。IrO配位中Ir - O键长的变化会引发晶格应变。提高退火温度会导致沿c轴的拉伸应变以及a轴和b轴上的压缩应变，从而使c/a比增大。增强晶格应变会降低c/a比，这有利于提高析氧反应活性。
