摘 要
质子交换膜燃料电池作为新型绿色能源技术，在未来电动汽车及分散式电站等领域将有非常广阔的应用前景。但目前制约燃料电池商业化的主要瓶颈是其高成本和低寿命，而贵金属氧还原催化剂的使用是成本的主要来源，也是决定燃料电池性能的关键因素。本文综述了一种新型的氧还原催化剂——铂基金属间化合物，介绍其结构特性以及Co组成对氧还原催化反应活性和稳定性的影响，最后对铂基催化剂的发展给出了展望。

Literature review on preparation of PtCo/Co3O4 nanocomposites and their electrocatalytic oxygen reduction properties
ABSTRACT
As a new green energy technology, proton exchange membrane fuel cell will have a very broad application prospect in the fields of electric vehicles and distributed power stations in the future. However, the main bottleneck restricting the commercialization of fuel cell is its high cost and low life. The use of noble metal oxygen reduction catalyst is the main source of cost and the key factor determining the performance of fuel cell. In this paper, a new type of oxygen reduction catalyst, platinum-based intermediates, is reviewed, and its structural characteristics and the effect of Co composition on the activity and stability of oxygen reduction catalysis are introduced.
