Photocatalytic and Antimicrobial Properties of Ag2O/TiO2 Heterojunction

ChemEngineering, 2019
Ag2O/TiO2 heterojunctions were prepared by a simple method, i.e., the grinding of argentous oxide with six different titania photocatalysts. The physicochemical properties of the obtained photocatalysts were characterized by diffuse-reflectance ...

Photocatalytic degradation of fractionated crude oil: potential application in oil spill remediation

Cogent Engineering, 2020
The current oil spill remediation strategies are costly and may be toxic to aquatic species and clean-up workers. There is, therefore, the need to look for alternative oil spill remediation strategies that are less costly and non-toxic.
