How to Enhance the Performance of Platinum on Alumina Catalysts?
1. Bimetallic Catalysts: Incorporating a second metal (e.g., palladium or rhodium) can enhance the catalytic properties and resistance to poisoning. 2. Promoters: Adding small amounts of promoters like cerium or lanthanum can improve the dispersion of platinum and its resistance to sintering. 3. Optimizing Preparation Conditions: Careful control of the impregnation, drying, calcination, and reduction steps can lead to better dispersion and higher activity.
