Dye-sensitized solar cell using a TiO2 nanocrystalline film electrode prepared by solution combustion synthesis

Wang C.M., Chungb S.L., National Cheng Kung University, TW

The nanocrystalline anatase TiO2 films were prepared and characterized in connection with their application to dye-sensitized solar cells. Solution combustion synthesis of TiO2 nanocrystalline film is based on hydrolysis, nitrated, and combustion reaction. The solution [...]

Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC

Yoo H., Kim S-H, Lee A.R., Kwak S-Y, Seoul National University, KR

In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]

Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2

Erdem A., Metzler D., Chou H.W., Lin H-Y, Huang C.P., University of Delaware, US

The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]

The effect of electric field on the surface of nanoparticles (TiO2 & SiO2) and its application to retardation of membrane fouling

Park S-E, Park S-J, Ry D-Y, Kwak J-W, Lee S-W., Park S-E, Park S-J, Associate Professor, Kyungwon University, KR

Since electrostatic device has been practiced for anti-foulant treatment effect on processing the industrial wastewater, the electric force is suspected to induce the alteration of surface charges of colloidal particles in the aspect of reducing [...]

The role of the synthetic procedure on the photoactivity of nanocrystalline TiO2

Ardizzone S., Bianchi C.L., Cappelletti G., Pirola C., Ragaini V., University of Milan, IT

The nanometer scale of the TiO2 plays a key role in affecting the photocatalytic performance of the material. In recent years a great deal of activity was dedicated, by the authors, to the study of [...]
