Porous ZnO/TiO 2 photocatalyst was prepared from porous TiO 2 coupling with ZnO by marinating method The photocatalytic activity was investigated by photocatalytic degradation of bromamine acid aqueous solution in the sun. The effects of ZnO adulterant proportion, the initial concentration of the bromamine acid aqueous solution and different light sources on the activity of the photocatalyst were discussed. The results suggest that in the sun, when the ZnO adulterant propor tion was 1%, the activity of the porous ZnO/TiO 2 photocatalyst was satisfying and superior to that of the porous TiO 2 . When the initial concentration of the bromamine acid aqueous solution was lower than 100mg/L, the result of photocatalytic degradation wa s better. The removal rate of chroma reached almost 100% and the removal rate of TOC over 75%. T he photocatalyst had a better activity under the sunlight than the UV light..

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.
