SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a
large surface area, which is widely employed as catalyst supports, absorbents, drug delivery
materials, etc. Since it has a lack of functionality, heteroatoms and organic functional groups
have been incorporated by direct or post-synthesis methods in order to modify their
functionality. The aim of this article is to review the state-of-the-art related to the use of SBA-
15-based mesoporous systems as supports for hydrodesulfurization (HDS) catalysts.

ABSTRACT SBA-16 is an interesting mesoporous silica material having nanopores and a
large surface area, which is widely employed as catalysts supports, absorbents, drug
delivery materials, etc. This material has attracted attention of catalytic researchers because
of its 3D structure consisting of ordered and interconnected spherical mesopores which
facilitates the transport of reactants and products without pore blockage. Since it has lack of
functionality, heteroatoms have been incorporated by direct or post-synthesis methods in …
