Ultraviolet-Visible (UV-Vis) Spectroscopy

, 2023
Ultraviolet-Visible (UV-Vis) spectroscopy is a versatile and powerful analytical method, which allows to investigate a wide variety of catalysts in both the liquid-phase and solid-state and their interfaces at elevated temperatures and pressures. In the case of solid catalysts, they can be studied in the form of powders (e.g., in 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.
