  • 4. Historical Hierarchy The field of nanocatalysis is not as new as could be expected from the current nanohype. Actually, its concept is known since the 1950s when the term nanotechnology was not even known. 1/16/2016 4Shakeel Khan, Imran Ali (UMT)
  • 5. Introduction Nanocatalysis is a process in which catalysis process use products of nanotechnology as a catalyst which are referred as “Nanocatalyst”. Nanocatalyst A catalyst composed of nanoparticles. Smaller than 100 nm in at least one dimension Porous compounds having pore diameters not bigger than 100 nm. Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. 1/16/2016 5Shakeel Khan, Imran Ali (UMT)

Nanomaterials offer many possibilities as catalysts to meet future demands in catalytic process technology in petroleum refining, petrochemical industry, and synthetic fuels production of the future. 2. The higher activity and better selectivity of nanocatalysts over traditional catalysts are attributed to their large specific surface area, high percentage of surface atoms and special crystal structures. 3. The development of nanocatalysts is increasingly supported by advances in preparation, characterization and testing of catalysts. 1/16/2016 25Shakeel Khan, Imran Ali (UMT)
