Zn–doped Titanium dioxide nanoparticles decorated on graphene sheets (ZT-GR) were synthesized via one step hydro-thermal method. This method was to mix graphene oxide with Zn-doped Titanium dioxide in ethanol through a certain. The photocatalytic activity of this catalyst was assessed by photodegradation of tetracycline to verify. Graphene oxide amount and hydrothermal temperatures were discussed in this article. We discovered that the photocatalytic activity of Zn–doped TiO2 nanoparticles decorated on graphene is much higher than Zn-doped TiO2 nanoparticles through photocatalytic degra-dation experiments. Zn-doped TiO2 on graphene sheets sample exhibited the highest photocatalytic activity when the gra-phene oxide amount was 5%, the hydrothermal temperature was 140 °C C, the hydrothermal time was 24 hours. Graphene decorating not only narrowed the band gap also increased the optical absorption into visible region. The optimal degradation rate of TC by using the catalyst of Zn–doped TiO2 nanoparticles decorated on graphene sheets was 98.5%. And graphene oxide decorating exhibited a good effect of degradation for tetracycline under visible 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.
