Beschreibung

Anwendung

• Sulfanyl Porphyrazines with Morpholinylethyl Periphery-Synthesis, Electrochemistry, and Photocatalytic Studies after Deposition on Titanium(IV) Oxide P25 Nanoparticles.: This study presents the synthesis and characterization of sulfanyl porphyrazines with morpholinylethyl peripherals. These compounds were deposited on Titanium(IV) oxide nanoparticles and evaluated for their photocatalytic properties, indicating potential applications in environmental photocatalysis and organic synthesis (Koczorowski et al., 2021).


• Gold-titanium(IV) oxide plasmonic photocatalysts prepared by a colloid-photodeposition method: correlation between physical properties and photocatalytic activities.: This research discusses the development of gold-Titanium(IV) oxide plasmonic photocatalysts using a colloid-photodeposition method. It explores the correlation between their physical properties and enhanced photocatalytic activities, suggesting applications in solar energy conversion and environmental remediation (Tanaka et al., 2012).


• Size-selective photocatalytic reactions by titanium(IV) oxide coated with a hollow silica shell in aqueous solutions.: This paper explores the use of Titanium(IV) oxide coated with hollow silica shells for size-selective photocatalytic reactions. The unique structural properties of these composites allow for selective photocatalytic degradation of organic pollutants in water, providing a novel approach to water purification (Ikeda et al., 2007).


• Photocatalytic activity of neat and silicon-doped titanium(IV) oxide nanofibers prepared by combined sol-gel and electrospinning techniques.: Investigates the photocatalytic performance of silicon-doped Titanium(IV) oxide nanofibers. These nanofibers show enhanced photocatalytic activity due to increased surface area and modified electronic properties, making them effective for pollution control and solar energy applications (Watthanaarun et al., 2007).


• Enhanced photocatalysis of pentachlorophenol by metal-modified titanium (IV) oxide.: Focuses on the photocatalytic degradation of pentachlorophenol using metal-modified Titanium(IV) oxide. The study demonstrates that the modification with metals significantly enhances the photocatalytic efficiency, offering a potent method for the detoxification of hazardous organic compounds in environmental applications (Lin et al., 2006).
