Aggregated Al TiO2 sphere s w ere synthesized by sol gel method using graphite sphere template. The diameter of the spheres is almost as large as 500 nm. Anatase TiO2 forms in all the samples, and doping of aluminum in the anatase TiO2 skeleton hinders crystal growing. The binding energies of Ti2 p 3/2 and Ti2 p 1/2 electrons dec r ease after doping aluminum in TiO2 spheres. The surface area of the aggregated Al TiO 2 spheres is doubled after doping 0.1% of aluminum in the TiO2 skeleton. The maximum photocatalytic degradation efficiency is obtained by the 0.1%Al TiO2 aggregated spheres. Decoloration efficiency on the 0.1%Al TiO2 aggregated spheres decreases slowly after several treating cycles..

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.
