Textural promoters work by integrating into the catalyst structure and modifying its physical attributes. They can achieve this in several ways:
Surface Area Enhancement: By increasing the surface area, textural promoters provide more active sites for the reaction, thereby improving the overall catalytic activity. Porosity Improvement: Enhanced porosity allows better diffusion of reactants and products, reducing mass transfer limitations and increasing reaction rates. Mechanical Stability: Textural promoters improve the robustness of the catalyst, making it more resistant to physical degradation during reaction conditions. Avoiding Sintering: By preventing the agglomeration of active particles, textural promoters help maintain a high surface area and active site dispersion.
