摘要：

Direct galvanic replacement of surface Cu with Au3+ in PtCu3 nanodendrites is applied to synthesize an Au-modified PtCu3 nanodendrite catalyst (PtCu3-Au), which shows both superior stability and excellent activity for the methanol oxidation reaction (MOR) and oxygen reduction reaction (ORR). The PtCu3-Au catalyst only lost 7% of its MOR activity and its ORR half-wave potential decreased 8 mV after 10 000 potential cycles.
