New equipment fabricated for controlling size of nanoclusters
10 July 2008Catalyst plays an important role in many techniques including hydrodesulfurization. Hydrodesulfurization is a technique in which sulfur from diesel or gasoline is removed by reacting it with hydrogen at high temperature and high pressure in the presence of catalyst.
As per the online edition of 9th July of the Journal of Physical Chemistry, researchers from U.S. Department of Energy (DOE), Brookhaven National Laboratory and Stony Brook University took a specific size molybdenum sulfide nanoclusters and deposited these clusters on gold surface. This device was used for controlling the number and type of atoms in a particular nanocluster.
For the current study, researchers took the cluster of 4 molybdenum and 6 sulfur atoms and deposited these on a gold surface. The researchers studied the catalyst activity on this cluster and have future plan to add more atoms of molybdenum and sulfur and see the affect on catalytic activity.
Once the researchers are able to find out the best-suited cluster, it will be used for making nanocatalysts, which will be used for hydrodesulfurization.
