A3.6 Nanoparticles in Catalysis
Nanoparticles are tiny - between 1 and 100 nanometres in size.
Catalytic particles are nearly always nanoparticles and they have a very large surface area per unit mass – so a big surface for a small amount of material.
Using Nano catalysts is expected to decrease the energy consumption in chemical processes and result in a “greener” chemical industry.
Nano catalysts are becoming increasingly important in a number of fields including:
- Improving the usefulness of petroleum fractions by removing and converting tar from petroleum into more useful molecules.
- Removing sulphur from petroleum fractions, especially diesel.
- The conversion of waste cooking oil into bio-diesel.
- Improvement of the efficiency of new generation fuel cells.
- To improve the storage and availability of hydrogen for internal combustion engines.
