• W3087577343 abstract "Abstract Although PtRu alloy nanocatalysts have been certified to possess excellent electrocatalytic performance and CO‐poisoning tolerance toward formic acid and methanol electro‐oxidation, the unaffordable usages of ruthenium (Ru) and platinum (Pt) have greatly limited their widespread adoption. Here, a facile one‐pot method is reported for implanting atomic dispersed Ru in PtNi colloidal nanocrystal clusters with different Ru/Pt/Ni molar ratios, greatly reducing the dosages of Pt and Ru, and further improving the catalytic performances for the electro‐oxidation of formic acid and methanol. Through simple control of the amount of Ni(acac) 2 precursor, trimetallic Ru 0.3 Pt 70.5 Ni 29.2 , Ru 0.6 Pt 55.9 Ni 43.5 , Ru 0.2 Pt 77.3 Ni 22.5 , and Ru 0.9 Pt 27.3 Ni 71.8 colloidal nanocrystal clusters (CNCs) are obtained. In particular, the Ru 0.3 Pt 70.5 Ni 29.2 CNCs exhibit excellent specific activities for formic acid and methanol electro‐oxidation, that is, 14.2 and 15.3 times higher, respectively, than those of the Pt/C catalyst. Moreover, the Ru 0.3 Pt 70.5 Ni 29.2 CNCs also possess better anti‐CO‐poisoning properties and diffusion ability than the other RuPtNi CNCs. The excellent formic acid and methanol electro‐oxidation activities of RuPtNi CNCs are ascribed to the optimal ligand effects derived from the Pt, Ni, and atomic dispersed Ru atoms, which can improve the OH adsorption ability and further the anti‐CO‐poisoning capability. This research opens a new door for increasing the electro‐oxidation properties of liquid fuels by using lower dosages of noble metals in Pt‐based catalysts." @default.
