How pore structure shapes catalyst performance

Learn more about Surface Area & Porosimetry

Surface area and porosity define how catalyst supports interact with active metals and reactants, making them fundamental to dispersion, diffusion, and overall catalytic efficiency. Understanding support pore structure across micro‑, meso‑, and macropores reveals how well metals anchor, how reactants access active sites, and how the support responds to thermal, mechanical, and chemical stress.

These textural parameters directly influence catalyst lifetime, resistance to sintering, and performance under real operating conditions. Gas adsorption and mercury intrusion techniques quantify pore size distribution, pore volume, and structural robustness, enabling researchers to evaluate how supports accommodate metal loading, withstand activation treatments, and maintain integrity during cycling. This insight is essential for designing supports that deliver stable dispersion, controlled mass transport, and predictable behavior in fixed‑bed, slurry, and fluidized systems
