Photocatalytic activity of the samples has been tested use methylene blue (MB) as the model pollutant and compared with P-25. Mesoporous SBA-15 and MSU-1 both prevent the anatase to rutile phase transformation and the growth of TiO_2 crystal grain.

• MSU-1负载的样品并不能显著提高二氧化钛的光催化活性，其光催化降解亚甲基蓝的能力远不如TiO_2/SBA-15的样品。
