Noodle-like mesoporous silica with a diameter of about 180 nm and a length of ca. 10 μm was prepared through sol-gel process by using poly(sodium 4-styrenesulfonate) (PSS)/cetyltrimethylammonium bromide (CTAB) complex as template. Parallel oriented regular mesopores with a diameter of around 2-4 nm are distributed along the wall of the particles, while the "worm-like" disordered mesopores can be found in the fringe part. This approach provides a new series of templates and a novel route to prepare inorganic mesoporous materials with special morphology.
