Abstract

Spindlelike mesoporous anatase titania particles were directly synthesized at a low temperature (95 degrees C) by using an aqueous peroxotitanium solution with polyacrylamide (PAM). The mesoporous titania had a BET-specific surface area of 89.6 m(2) g(-1) and showed high crystallinity, thermal stability, and good photocatalytic activity in the degradation of rhodamine B. PAM, as an additive, was confirmed to be crucial in the evolution of the specific structure, morphology, and crystalline phase, and a possible formation mechanism was suggested.
