“…11,34 Additionally, properties such as particle size, morphology and porosity also inuence directly the performance of the electrocatalyst and can be controlled by the synthesis method. 12,23 Several preparation methods of PtRh catalysts were proposed in the literature such as electrodeposition 17,35 microwave-assisted, 12 hydrothermal synthesis, 36 polyol method, 31,[37][38][39] and, borohydride-reduction method. [40][41][42][43][44] However, to avoid any limitation in activity due to the remained organic surfactants on the catalysts, a suitable synthesis approach is required.…”
