Figure 3. Structure sensitivity of the OER activity on the double perovskites.

Figure 3

(a) OER activity in 0.1 M HClO4 of Sr2YIrO6 DP in comparison with Sr2IrO4. (b) OER activity in 0.1 M HClO4 of Ba2PrIrO6 DP in comparison with Pr3IrO7. (c) Effect of the A and B′ cation substitution on the OER activity in 0.1 M HClO4 of the Ir DPs. The benchmark activity of IrO2 nanoparticles is shown for comparison. Measurements performed under steady-state conditions. The values in the plot are the average of three independent measurements and the error bars correspond to the s.d.
