Catalyst Pore Structure
Why pore size and connectivity affect access to internal catalytic surface.
Industrial note: catalyst performance depends on the specific chemistry, reactor, feed and approved process conditions. This site explains system concepts rather than operating recipes.
What this topic covers
Why pore size and connectivity affect access to internal catalytic surface.
Core catalyst ideas
Porous catalysts can provide far more internal surface than external geometry suggests.
Molecules must diffuse through pores to reach internal active sites.
Deposits or structural changes can block access even when total platinum remains present.
System tradeoffs
Supports, particles, pores and structured substrates can change both activity and durability.
Performance evidence
Higher surface area can improve platinum utilization but may reduce thermal or structural stability.
Lifecycle perspective
Commercial catalyst manufacturing uses specialized chemistry and controlled processing not reproduced here.
