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.

is a process in which catalysis process
use products of nanotechnology as a catalyst which
are referred as “Nanocatalyst”.
A catalyst composed of nanoparticles.
Smaller than 100 nm in at least one dimension Porous
compounds having pore diameters not bigger than
is the increase in the rate of a chemical
reaction due to the participation of an additional
substance called a catalyst.

Principle of Catalysis
1. Increases the rate of chemical reaction by
reducing the required activation energy and alter the
required reaction temperature.
2. Catalyst provide a site for the reactants to be
activated and interacted together while leaving the
catalyst surface unchanged after the reaction.
1/16/2016 20Shakeel Khan, Imran Ali (UMT)
Principle of Catalysis
3. Normally catalyst surface must have the high
active energy, right structure, and enough spaces.

Synthetic Fuels Production
1/16/2016 24Shakeel Khan, Imran Ali (UMT)
1. 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.
