We reported the design of a core-shell Cu@PtCu electrocatalyst consisting of dendritic PtCu alloy branches assembling on Cu core nanocrystals. The Cu@PtCu electrocatalyst shows superior electrocatalytic performance toward a methanol oxidation reaction. Its specific activity and mass activity can reach 3.56 mA cm and 1568 mA mg, which are 4.8 and 7.1 times higher than those of a commercial 20% Pt/C catalyst.
我们报道了一种核壳结构的Cu@PtCu电催化剂的设计，该催化剂由在铜核纳米晶体上组装的树枝状PtCu合金分支组成。Cu@PtCu电催化剂对甲醇氧化反应表现出优异的电催化性能。其比活性和质量活性分别可达3.56 mA cm和1568 mA mg，分别是商业20% Pt/C催化剂的4.8倍和7.1倍。
