1具有可控表面结构和组成的PtNi八面体纳米粒子的氧还原活性研究(英文)显示文摘双金属催化材料的催化性质可以通过在原子水平下控制材料的表面结构和组成进行有效调节.本文发展了一种普适性的方法合成具有高度分散性、洁净表面和可调的表面结构和组成的Pt_xNi_(1-x)八面体纳米粒子.研究发现在反应过程中,通过增加Ni前驱体的含量,合成的Pt_xNi_(1-x)八面体纳米粒子的(111)晶面的凹陷程度逐渐加大.我们系统研究了Pt_xNi_(1-x)八面体纳米粒子的表面结构或组成与其氧还原电催化活性之间的相互关系.电化学研究结果表明所有的Pt_xNi_(1-x)八面体纳米粒子均表现出比标准商业Pt/C催化剂更高的氧还原活性.更重要的是,我们发现Pt_xNi_(1-x)八面体纳米粒子的表面结构和组成对其氧还原电催化活性具有很大的影响.研究发现,具有轻微(111)晶面凹陷程度的Pt_1Ni_1八面体纳米粒子显示出最高的氧还原电催化活性.在0.9 V(相对于标准氢电极)电势条件下,Pt_1Ni_1八面体纳米粒子的氧还原质量活性和面积活性分别为标准商业Pt/C催化剂的7.0和7.5倍.该研究不仅提供了一种普适性的方法合成具有高度分散性、洁净表面和可调的表面结构和组成的Pt_xNi_(1-x)八面体纳米粒子,同时可为理解催化材料的结构-性质相互关系规律提供指导.逯一中 Larissa Thia Adrian Fisher Chi-Young Jung Sung Chul Yi 王昕 2017Science China Materials2017,60,11:3
