Heterogeneous Platinum Catalysis
Why solid platinum catalysts are widely used with gas- and liquid-phase reactants.
What this topic covers
Why solid platinum catalysts are widely used with gas- and liquid-phase reactants.
Core catalyst ideas
In heterogeneous catalysis, reactants interact with a catalyst in a different phase, commonly a solid surface.
Surface area and accessible active sites matter because reactions occur at or near the catalyst surface.
Transport of molecules to and from active sites can influence apparent reactor performance.
System tradeoffs
Activity and selectivity are different performance dimensions, and neither alone defines a good industrial catalyst.
Performance evidence
Catalyst value comes from the total process outcome rather than the amount of platinum present.
Lifecycle perspective
