The surface properties of aluminated meso–macroporous silica and its catalytic performance as hydrodesulfurization catalyst support

Abstract Aluminated mesoporous silica was prepared by multiple post-grafting of alumina onto uniform mesoporous SiO2, which was assembled from monodisperse SiO2 microspheres. Hydrodesulfurization (HDS) catalyst was prepared by loading Ni and Mo active components onto the aluminated uniform mesoporou...
