摘　　要：铂基催化剂具有活性高、选择性好、电化学稳定性佳等优点,在工业催化和燃料电池领域具有非常重要的地位。然而,由于成本较高、可用性较低限制了其实际发展。因此,有必要优化铂基催化剂的利用率,设计低成本和高稳定性的铂基催化剂。本研究首先介绍了在燃料电池催化剂领域具有应用前景的Pt-Pd-Ni系合金电催化剂的发展和研究现状,然后详细介绍了Pt-Pd-Ni体系的三个二元系相图与热力学评估数据和研究进展,并对Pt-Pd-Ni三元系的一些实验研究进展和今后的研究工作提出展望,对不同相结构对催化性能的影响进行了分析和讨论。通过Pt-Pd-Ni系相图和相结构等的研究将为燃料电池用新型贵金属合金催化材料的设计及工业应用奠定理论和实验基础。Platinum based catalysts have the advantages of high activity,good selectivity,and excellent electrochemical stability,and play the very important role in industrial catalysis and fuel cell fields.However,its actual development is limited by high costs and low availability.Therefore,it is necessary to optimize the utilization rate of platinum based catalysts and design low-cost and high stability platinum based catalysts.This study first introduces the research status of Pt-Pd-Ni alloy electrocatalysts which has significant application prospects in the field of fuel cell catalysts,and then details introduction of the three binary phase diagrams and thermodynamic research progress of the Pt-Pd-Ni system,as well as some experimental research progress of the Pt-Pd-Ni ternary system,and puts forward prospects for future research work,and the influence of different phase structures on catalytic performance is analyzed and discussed.The study of Pt-Pd-Ni phase diagram and phase structure will lay a theoretical and experimental foundation for design and industrial application of new precious metals catalytic materials for fuel cells.
