Synthesis and characterization of Ag-ZnO@Clinoptilolite for photocatalytic degradation of Tetracycline [PDF]

open access: yesJournal of Applied Research in Water and Wastewater, 2019
In this research, degradation of Tetracycline by Ag doped ZnO based on Clinoptilolite (Ag-ZnO@CP) as photocatalyst was investigated under visible light. To synthesize of photocatalyst, the wetness impregnation method was used.

Rectifying ZnO–Na/ZnO–Al aerogels p-n homojunctions [PDF]

open access: yesJournal of Materials Science: Materials in Electronics, 2022
Semiconductor ZnO aerogels were synthesized by a sol-gel process with different concentrations (2.5-7.5 wt.%) of Al (n-type) or Na (p-type) and dried under supercritical CO2. The materials were calcined at 500 °C to remove the organic content and to crystallize the ZnO.
