Abstract
This article delves into the preparation and performance optimization of palladium based catalysts. Firstly, in the introduction section, the article elaborates on the research background and significance of palladium based catalysts, summarizes the current research status, and introduces the research methods and technical routes adopted. Then, the preparation methods of palladium based catalysts were discussed in detail, including impregnation, coprecipitation and sol gel methods. By optimizing the preparation process, the efficiency and quality of catalyst preparation have been improved. Among them, the optimization of the impregnation method preparation process makes the catalyst load more uniform, the adjustment of the coprecipitation method preparation parameters improves the catalyst dispersion, and the sol gel rule obtains a more stable catalyst structure by precisely controlling the preparation process. Subsequently, the article characterized the structure of palladium based catalysts, analyzed their morphology, structure, and surface chemical properties, and established an evaluation method for catalytic activity. These analyses provide a theoretical basis for optimizing the performance of catalysts. In terms of performance optimization strategies, the article proposes multiple optimization strategies from three aspects: the selection and modification of carrier materials, the mechanism of co catalysts, and the optimization of heat treatment processes. By selecting appropriate carrier materials and co catalysts, as well as optimizing the heat treatment process, the catalytic activity and stability of palladium based catalysts have been significantly improved.
