| 7499 | 217 | IrO2 | 1.7 | 0.3 | nm | DLS | The average size of IrO2 nanoparticles was 1.7 ± 0.3 nm by counting more than 200 nanoparticles. The monodisperse IrO2 nanoparticles on GO indicated that GO had effectively inhibited the aggregation of IrO2 nanoparticles. There were no unsupported IrO2 nanoparticles observed, which indicated that the GO was an excellent support. |
