“…There are many studies regarding noble-metal-based nanocrystals prepared by the coreduction route, such as nanopolyhedrons (Pt-Pd, Rh-Pd, Pt 3 M), concave structures enclosed by high-index facets, metallic dendritic nanostructures, nanosheets, nanoplates, and core-shell nanostructures. [46][47][48][49][50][51][52][53][54][55][56][57][58][59] As compared to NPs enclosed by low-index facets, concave nanocrystals that expose high-index facets are expected to show enhanced catalytic properties because several atoms and/ or kinks with low coordination numbers are distributed on the surface, which possess higher activity. However, during the synthesis process, high-index facets tend to rapidly vanish due to their high surface free energy.…”

“…prepared ultrathin, ternary PtRuFe nanowires for both MOR and formic acid oxidation reaction (FAOR). Other morphology beyond nanowires was also exploited: bimetallic AuPd dendritic alloyed nanocrystals with large ECSA were prepared by one‐pot co‐reduction method, exhibiting excellent activity and stability for hydrogen oxidation reaction (HOR) . PdRu/P nanoparticle network was fabricated via a facile method using hydrazine hydrate as the reducing agent.…”

Polymer electrolyte fuel cells (PEFCs) are among the most advanced energy technologies with low operating temperatures, high energy densities, ease of transportation and storage. However, the deficiencies such as low activity and high cost of the electrocatalysts at anodes greatly hinder their commercialization. The commonly used carbon black supports lack the capacity of regulation over the supported noble metals towards efficient electro‐catalytic oxidation of fuels. In this Mini‐Review, the prerequisite factors in advanced supports are outlined, ranging from self‐supported precious metal alloys as well as non‐noble metal materials, while simultaneously revealing the superiorities of some advanced supports beyond carbon black in terms of electronic conductivity, synergy with surface precious metals, chemical and electrochemical stability, and other possible interactions. The effects arisen from microscopic morphology, nano‐structure, and composition on the electrocatalytic activity/stability are also discussed. Finally, several of the most promising supports are highlighted, and the research trends of synergistic supports in future PEFCs are predicted.
