title: Porous Tetrametallic PtCuBiMn Nanosheets with a High Catalytic Activity and Methanol Tolerance Limit for Oxygen Reduction Reactions.
abstract: Porous PtCuBiMn nanosheets are developed with a thickness of ≈3-4 nm. The specific and mass activities of these nanosheets are ten and seven times greater than that of commercial Pt/C catalyst, respectively. PtCuBiMn nanosheets demonstrate superior catalytic performance for the oxygen reduction reaction, as well as resistance to methanol cross-over effects, suggesting that it is a promising catalyst for direct methanol fuel cells.
