Alumina nanotube/nanorod supported hydrodesulfurization nanocatalyst, method of preparation and application

A hydrodesulfurization nanocatalyst comprising:

• a nanostructured alumina material;
• at least one metal selected from group VI B of the periodic table of elements, and at least one metal selected from group VIII B of the periodic table of elements, wherein the molar ratio of the metal selected from group VI B of the periodic table of elements to the metal selected from group VIII B of the periodic table of elements is from about 0.2 to about 0.5 and wherein the metals are present on the nanostructured alumina material in a form of multilayer nanoclusters wherein the catalyst further comprises zeolite HY and B2O3 in a ratio of about 1:0.5.
