Abstract: In the present work, mesoporous SBA-16 was synthesized using tetraethyl orthosilicate as the silica source, triblock co-polymer Pluronic F127 as template and cetyltrimethylammonium bromide (CTAB) as co-template respectively. The surface modification of SBA-16 was carried out by impregnation of zinc oxide. As-prepared SBA-16 and ZnO/SBA-16 were characterized by FTIR, TGA, BET and SEM techniques. Characterization techniques revealed that zinc oxide was highly dispersed into/over the well-ordered mesoporous channels and even after impregnation of zinc oxide, mesostructure of SBA-16 was still retained together with high thermal stability, high surface area, large pore volume and uniform pore size. The catalytic activity of the ZnO/SBA-16 was investigated for degradation of methylene blue dye and analyzed by UV-Vis spectroscopy. The results showed that as-prepared ZnO/SBA-16 exhibited excellent catalytic activity towards degradation of crystal violet and methylene blue dye.
