1. Catalyst Material: Selection of appropriate catalyst material with high intrinsic activity. 2. Layer Thickness: Optimizing the thickness of the catalyst layer to balance activity and stability. 3. Porosity: Designing the porosity to enhance mass transfer and reduce diffusion resistance. 4. Support Material: Choosing suitable support materials that provide mechanical stability and enhance activity. 5. Functionalization: Incorporating functional groups or secondary components to improve catalytic properties.
