【Abstract】 Pt catalyst is the most commonly used electrode materials for fuel cells at low temperature. The internal relations and rules between the surface structure, electronic properties and catalytic performance are the basis for the design and development of high activity, high stability and high selectivity of electro-catalyst. In recent years, on the research results of oxygen reduction reaction, the new technology for the preparation of highly dispersed Pt catalysts at home and abroad have been summarized and focused on the research progress of catalyst particle size, composition, structure and properties of alloy control properties. At last, the trends of development in the field are also discussed.更多还原
