The choice of catalyst in a flow cell depends on the specific reaction being carried out. Common types include:
1. Homogeneous Catalysts: These are catalysts that are in the same phase as the reactants, typically dissolved in a liquid. They are easily integrated into flow systems but may require separation steps after the reaction. 2. Heterogeneous Catalysts: These are solid catalysts that facilitate reactions in liquid or gas phases. They are often supported on materials like silica or alumina to increase surface area and activity. 3. Biocatalysts: Enzymes and other biological catalysts can be used in flow cells for highly specific and selective transformations.
