摘要：
Thermostability of P25 nanoparticle was carried out by ascending thermal annealing. The growth of particle was observed and the activation energy of phase transition was calculated. The photocatalytic reactivity was measured in terms of the degradation rate of methylene blue. Results indicated that the specific surface area and the aggregation of TiO2 are much important factors than the crystal phase on the photo-decoloration reaction.
