Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]

Nanoparticle Characterization and Analysis of Airborne Titanium Dioxide in Powdered Cosmetics

Cavaliere M.R., Compton S.P., MVA Scientific Consultants, US

In this study, several powdered cosmetic products were purchased and evaluated for the presence of TiO2 nanoparticles first by automated particle sizing using scanning electron microscopy (SEM) with chemical typing by energy dispersive spectroscopy (EDS) [...]

An investigation on the aggregation phenomena of Titanium dioxide nanoparticles in natural waters: role of ionic strength, organic matter and natural colloidal particles

Romanello M., Luppi V.A., Bertini L., Fidalgo de Cortalezzi M., Instituto Tecnológico de Buenos Aires, AR

The aggregation behavior of TiO2 nanoparticles under conditions normally encountered in natural waters was investigated. Aggregation kinetics and size distribution was determined by DLS using a Nanosizer ZS, Malvern, UK. SEM images were also collected. [...]

Solution Growth of Nanostructured Ceramic Films

Cho J., State Univ of New York (SUNY) at Binghamton, US

Low-temperature processing that can lead to the development of highly-functional, strain-tolerant ceramic films will offer innovative solutions for the use of ceramic thin films and coatings. Current developments in organic and flexible electronics make the [...]

Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Wu K.R., Hung C.H., Yeh C.W., Sun J.C., Hsu C.J., National Kaohsiung Marine University, TW

In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Synthesis of TiO2 Nanotube Arrays for Hydrogen Production from Photo-Assisted Water Splitting Reaction

Kawde A.Y., Vats A., Shende R.V., Puszynski J.A., South Dakota School of Mines & Technology, US

This study focuses on the synthesis of TiO2 nanotube arrays and its application for hydrogen generation from photo-assisted water-splitting reaction. In the synthesis approach, an nt-TiO2/Ti/nt-TiO2 structure was synthesized using electrochemical anodization in fluorine (F-) [...]
