Mechanism investigation on the enhanced photocatalytic oxidation of nonylphenol on hydrophobic TiO2 nanotubes

Encapsulation and Release of Doxorubicin from TiO2Nanotubes: Experiment, Density Functional Theory Calculations, and Molecular Dynamics Simulation

“…Generally, a water contact angle less than 90° is expected for hydrophilic materials while contact angles between 90 and 150° represent moderate to strong hydrophobicity, and superhydrophobic materials display values between 150° and 180° . Thus, the water contact angle is excellent although the measure is simple for the hydrophilic or hydrophobic nature of a material.…”

“…Thus, the water contact angle is excellent although the measure is simple for the hydrophilic or hydrophobic nature of a material. TiO 2 surfaces usually show high wettability and very small contact angles in keeping with their general hydrophilic character. − At the same time, the wettability of the TiO 2 nanotubes depends on the tube dimensions, surface roughness, and the presence of intrinsic impurities or impurities incorporated from electrolytes. − For example, reactive plasma or UV light treatment greatly enhanced the hydrophilicity of TiO 2 nanotubes . PEG as a coating or capping agent might drastically modify the hydrophilicity and thus the wettability of surfaces and tube entrances, which is pivotal for drug release. , …”

Effects of Degradation of Nonylphenol in Waste Water by Strong Ionization and Its Degradation Products on Sex Differentiation in Zebrafish

“…In recent years, some advanced oxidation degradation of refractory organic pollutants in wastewater has become a hot research technology. Traditional advanced oxidation technologies, such as Fenton method, do not have a high degradation efficiency for NP, while some methods combining nanoscale catalysts have improved the degradation efficiency of NP, but the service life [7] and recovery of catalysts [8] have become new problems. Some studies have shown that strong ionization dielectric barrier discharge (SID) has a high removal effect on the refractory organic pollutants in sewage without the addition of reagents or catalysts.…”

Mechanism and Pathway of Nonylphenol Degradation in Aqueous Solution by Dielectric Barrier Discharge

“…In this case, advanced oxidation technology (AOPs) has gradually become the focus of research on NP degradation. Fenton methods with catalysts have become the new favorite of AOPs, the new methods are indeed effective in the degradation of nonylphenol [8], but the problems of its service life and recovery are still difficult to solve [9]. In contrast, low temperature plasma technology does not need reagents or catalysts, and the degradation process is highly efficient and non-selective, which shows great prospects in the treatment of such refractory organic compounds.…”
