| Abstract |
Pt-based nanomaterials are well-known for catalyzing methanol oxidation reaction (MOR) in the anode of DMFCs. However, high cost, low abundance, and CO poisoning of Pt-based catalysts impede the practical use of DMFCs. Therefore, fabrication of economical Pt-based alloy catalysts toward the MOR has been intensively investigated. Among the possible approaches, trimetallic nanostructures have received great interests due to their unprecedented synergistic effect among multiple components on the surfaces. Recently, hollow- and cage-like nanostructures have been explored in order to achieve large Pt dispersion on their active surface sites. In this work, we combined these activity-boosting strategies to build Ru branched RuPtCu ternary alloy nanocage as a promising MOR catalyst. Electrochemical MOR activity and stability of the Ru branched RuPtCu nanocages are greatly promoted compared to those of PtCu and RuPtCu nanocages and the state-of-the-art Pt/C. We expect that this synthetic methodology will pave the way for further development of multicomponent nanoframe catalysts toward important electrocatalytic processes. |
