Multifunctional catalysts are significant for several reasons: 1. Efficiency: They can carry out multiple reactions in a single step, reducing the number of reactors and separation processes needed. 2. Selectivity: By carefully designing the catalyst, it is possible to achieve high selectivity for desired products, minimizing waste. 3. Sustainability: Multifunctional catalysts can lower energy consumption and reduce the need for harmful reagents, aligning with green chemistry principles. 4. Cost-Effectiveness: Fewer steps and materials mean lower operational costs and capital investment.
