However, the homogeneous Pt-based catalysts have problems such as high cost and relatively low electrocatalytic performance. Therefore, the preparation of low-cost and high-efficiency Pt-based catalysts is currently a hot research topic and difficult point.In this paper, we will study the preparation methods of Pt-based catalysts, including commonly used precipitation, reduction, hydrothermal, sol-gel methods, and compare their advantages and disadvantages. At the same time, we will also study the performance of Pt-based catalysts in electrocatalytic reactions, and evaluate the performance of Pt-based catalysts under different preparation methods through electrocatalytic performance testing.The purpose of this study is to develop a Pt-based catalyst preparation method with high electrocatalytic performance, and provide theoretical and practical basis for the application of Pt-based catalysts in electrocatalytic reactions.精品文档---下载后可任意编辑Keywords: Pt-based catalysts; electrocatalytic performance; preparation methods; fuel cells; electrolytic water production of hydrogen.
