McPts纳米催化剂的电催化氧还原性能
Electrocatalytic oxygen reduction performance of McPts nanocatalyst
摘要
Abstract
McPts(M =Ni,Co,Cu and Ag) nanoparticles with different thickness of Pt shell were prepared by two-step chemical reduction method.The structure and composition of particles were characterized by XRD,XPS and TEM tests.The catalytic activity of oxygen reduction reaction(ORR) and methanol-resistance of nanoparticles were tested by the potentiodynamic test.The fabricated McPts nanoparticles were spherical in shape,the average diameter was 35 nm,average thickness of Pt shell was about 6 nm.The activity of ORR of M =Ni,Co was increased and those of M =Cu,Ag were decreased when compared with Pt/C.The methanol tolerance of McPts/C was promoted Co,Cu and Ag were the core.关键词
