Dongshuang Wu, Dr. Minna Cao, Min Shen and Prof. Rong Cao Sub-5 nm Pd–Ru Nanoparticle Alloys as Efficient Catalysts for Formic Acid Electrooxidation ChemCatChem 6
The presence of ruthenium: A simple preparation method of Pd–Ru nanoparticle alloys over the whole composition range is presented. Their confined sizes of 3–5 nm are favorable in direct formic acid fuel cells (DFAFCs). The alloyed Ru causes a downshift in d-band center rendering these Pd–Ru alloys highly active and stable towards formic acid oxidation.
