近年来,随着纳米技术的发展,纳米材料由于其独特的性质已被广泛应用于各种领域.纳米催化剂的大小、形貌、组成和结构是影响材料性质的主要参数.本文主要介绍铂(Pt)及Pt基催化剂中PtPd、FePt、PtNi合金组分和形貌对氧还原的活性和稳定性的影响.Pt催化剂主要通过控制形貌改变氧还原性能.Pt基催化剂的组分和形貌的不同会导致其催化性能的不同,只有特定组分或形貌的催化剂才具有与商业Pt/C相媲美的氧还原性能.
In recent years, with the development of nanotechnology, nanomaterials have been widely used in various fields because of their unique properties.The size, morphology, composition and structure of nanocatalysts are the main parameters that affect the properties of materials.In this paper, Pt) and Pt-based catalysts on the activity and stability of oxygen reduction.Pt catalyst mainly changes the oxygen reduction performance by controlling the morphology.The composition and morphology of the Pt-based catalyst Will lead to the different catalytic properties, only the specific components or morphology of the catalyst has comparable with commercial Pt / C oxygen reduction performance.
