A sol-gel method was used for the synthesis of La2Ti2O7 photocatalysts using PEG4000 as the template. The materials are composed of the main perovskite La2Ti2O7 phase and a very small amount of La0.66TiO2.993 phase. The crystallite size of La2Ti2O7 is almost not influenced by the addition of PEG4000. Small mesopores are formed in the PEG4000 modified materials. The specific surface area is gradually enlarged with increasing amount of PEG4000. A schematic illustration of photocatalytic degradation mechanism is suggested for La2Ti2O7. The maximum photocatalytic activity is found on the La2Ti2O7 prepared using 1.5 g PEG4000..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
