There are several strategies to increase catalyst loading: 1. Increase the amount of catalyst: This is the most straightforward method, involving the addition of more catalyst to the reaction mixture. 2. Use highly active catalysts: Employing catalysts with higher intrinsic activity can achieve the same effect as increasing the amount of a less active catalyst. 3. Optimize catalyst support: Enhancing the surface area or modifying the support materials can improve catalyst dispersion and availability. 4. Engineered catalyst structures: Using nanostructured catalysts or catalysts with specific geometries can increase the effective loading without merely adding more material.
