Abstract:In this work, the PtCu electrocatalyst supported on graphdiyne (PtCu/GDY) nanocomposite was synthesized for methanol oxidation reaction (MOR). The results demonstrated that the obtained PtCu/GDY catalyst has a good dispersion on graphdiyne. The electrochemical experiments indicated that the PtCu/GDY displayed a superior electrocatalytic activity towards MOR with a high mass activity of 336 mA mg(-1). Furthermore, the presence of GDY can significantly improve the CO tolerance property of PtCu for MOR, which facilitating OHads generation from H2O decomposition. Therefore, the PtCu/GDY electrocatalyst offers an exciting opportunity to be commercialization of direct methanol fuel cells.
