Dopants are used in catalysis to achieve various objectives such as:
1. Enhancing Activity: By introducing dopants, the number of active sites on the catalyst surface can increase, leading to higher catalytic activity. 2. Improving Selectivity: Dopants can modify the electronic and geometric properties of the catalyst, making it more selective towards desired products. 3. Increasing Stability: Certain dopants can improve the thermal and chemical stability of catalysts, thereby extending their operational life. 4. Reducing Costs: By using cheaper dopants, the overall cost of the catalytic material can be reduced without compromising performance.
