    Materials with Porous Architectures
    •  Porous materials can be 
       engineered as catalysts
    •  High surface areas
        Inorganic Frameworks ca. 100-
           600 m3/g
        Metal-organic Frameworks 
           (MOFs) up to 10 400 m3/g
    •  Maximise framework – 
       substrate interactions
    •  High potential for strategic 
       positioning of active sites 
       within frameworks
