A newly developed photoelectrochemistry analytical methodology was applied to selective detection of the immunoreaction between anti human IgG and human IgG. The method is based on the principle of the dye-sensitized solar cell, using an NHS-ester derivative of ruthenium polypyridine as the signal indicator and nanoparticle TiO2 as electrode material. After performing the affinity reaction, photoelectrochemical measurement showed that anodic photocurrent was turned on and off repeatedly by control of incidental visible-light, due to light absorption of the ruthenium compound immobilized on the electrode. Owing to its separate source for excitation (light) and detection (current) and the use of electronic detection, the photoelectrochemistry system is expected as a sensitive and low cost method for the detection of biological affinity interaction. ©2010 IEEE.

Commercial WO 3 powder was annealed in air at four different temperatures and characterized by XRD and BET. The samples were used for the photooxidation of H 2 O to O 2 under visible light irradiation (λ > 420 nm) in the presence of IO 3- and the evolved gases were analyzed by gas chromatography. The results showed that the WO 3 photocatalyst of monoclinic phase, which was obtained by annealing at 750 °C for 4 h, displayed the best activity in terms of O 2 evolution among all the samples. Moreover, the activity was also found to be slightly affected by the grain size of the WO 3 samples. © 2009 Elsevier B.V. All rights reserved.

Four types of novel counter electrodes based on flexible metal and plastic substrates have been fabricated and performance characteristics of the dye-sensitized solar cells (DSCs) composed of these counter electrodes have been investigated. The DSCs composed of the counter electrodes based on a stainless steel substrate, a nickel sheet and a conducting plastic film, respectively. The solar conversion efficiencies of 5% have obtained. The counter electrode based on the stainless steel substrate has the merit of improving the conversion efficiency of the DSCs by reducing its internal resistance. The stabilities of the metal and plastic substrates in the electrolyte solution were tested. The long-term stabilities of the DSCs based on these novel counter electrodes were examined, and the routes to improve the long-term stabilities of the DSCs were presented.

A highly efficient dye-sensitized solar cell (DSC) was fabricated using a nanocrystalline nitrogen-doped titania electrode. The properties of the nitrogen-doped titania powder, film, and solar cell were investigated. The substitution of oxygen sites with nitrogen atoms in the titania structure was confirmed by X-ray photoemission spectroscopy (XPS). The UV-vis spectrum of the nitrogen-doped powder and film showed a visible light absorption in the wavelength range from 400 to 535 nm. An enhancement of the incident photon-to-current conversion efficiency (IPCE) in the range of 380-520 nm and 550-750 nm was observed. An 8% overall conversion efficiency has been achieved. The results of the stability test indicated that the solar cell fabricated by the nitrogen-doped titania exhibited great stability. © 2005 American Chemical Society.

Several types of counter electrodes based on flexible metal and plastic substrates for dye-sensitized solar cells (DSCs) have been investigated. The DSCs composed of the counter electrodes based on a stainless steel substrate, a nickel sheet and a conducting plastic film, have obtained conversion efficiencies comparable to that based on the conducting glass. The counter electrode based on the stainless steel substrate has the merit of improving the fill factor and conversion efficiency of the DSC by reducing its internal resistance. The counter electrode based on a polyester film can be aimed at lower cost markets. These counter electrodes based on the metal and plastic substrates are applicable for flexible DSCs. © 2004 Elsevier B.V. All rights reserved.

The properties of several types of counter electrodes based on metal, plastic, and glass substrates for use in dye-sensitized solar cells (DSCs) were investigated. High conversion efficiencies of ca. 5% for the DSCs based on a stainless steel, nickel sheet and conducting plastic film were obtained. The sheet resistances of the substrates and the platinized counter electrodes were measured. For the large-size DSCs based on the stainless steel counter electrode, the fill factor and conversion efficiency were improved by 20% by reducing the internal resistance of the cell. The stability of the metal and plastic substrates in the electrolyte and the long-term stability of the solar cell based on these counter electrodes were examined. The results revealed that the stainless steel, Ni, and ITOPEN electrodes have good stabilities in the electrolyte. © 2004 Elsevier B.V. All rights reserved.

Effect of the thickness of the Pt film coated on a counter electrode on the performance of a dye-sensitized solar cell 査読有り

Fang X., Ma T., Guan G., Akiyama M., Kida T., Abe E.

記述言語：英語掲載種別：研究論文（学術雑誌）

The effects of the thickness and morphology of a Pt film coated on a counter electrode on the performance of a dye-sensitized solar cell (DSC) were investigated. Deposition of a Pt film ranging in thickness from 2 to 415 nm gradually decreases the sheet resistance of the counter electrode. No significant difference in the charge-transfer resistance at the electrolyte|counter electrode interface was observed for a Pt film thickness ranging from 25 to 415 nm. A high energy conversion efficiency of approximately 5% can be obtained for DSCs based on a counter electrode with a very thin Pt film of 2 nm, as well as with a 415-nm thick Pt film. These results are important for reducing production costs by reducing the required amount of expensive platinum. © 2004 Elsevier B.V. All rights reserved.

The effects of the thickness of Pt film on the property of platinized counter electrode and the performance of the dye-sensitized solar cell (DSC) were investigated. The Pt film sputtered on an FTO glass is constructed of Pt particles, and the grain size of the Pt particles gradually increased with the increase in the Pt film thickness. When the Pt film thickness exceeds 100 nm, further Pt deposition has no significant effect on the conductivity improvement. In the range between 10 and 415 nm, the Pt film thickness has no significant influence on the performance of the DSC. A high conversion efficiency of ca. 5% was obtained by the DSC composed of the counter electrode with Pt film of 10 nm thickness. These results are important for reducing the production cost by reducing the required amount of expensive platinum. © 2004 Elsevier B.V. All rights reserved.

International Journal of Hydrogen Energy 29 ( 3 ) 269 - 274 2004年03月

記述言語：英語掲載種別：研究論文（学術雑誌）

Photocatalytic hydrogen production from a digested sewage sludge solubilized in hot-compressed water (573K) was investigated in order to develop a low-cost sacrifice agent for CdS-based photocatalysts from biomass. H 2 evolution occurred over a LaMnO3/CdS composite photocatalyst under Xe lamp irradiation from water containing the solubilized sewage sludge and the amount of evolved H2 reached more than 30 mmol/g-catalyst for a 200 h-reaction; on the other hand, no H2 was formed in the absence of the solubilized sewage sludge. The H2 evolution rate was comparable to that when typical Na2S-Na 2SO3 sacrifice agents were used, suggesting the applicability of a biomass-derived sacrifice agent for photocatalysis. Organic compounds, such as methanol and formic acid, contained in the solubilized sewage sludge are responsible for the H2 evolution observed. © 2003 International Association for Hydrogen Energy.

The photocatalytic activity of a CdS/ETS-4 composite for hydrogen production from water under visible light irradiation (λ>420 nm) was investigated. It is found that nano-sized CdS particles embedded in ETS-4 zeolite nano-pores showed stable photocatalytic activity in an aqueous solution containing Na 2 S and Na 2 SO 3 electron donors and the energy conversion efficiency (ECE) was improved by combining CdS with ETS-4. The results suggest that the encapsulation of CdS in ETS-4 zeolite is effective for improving the activity as well as the stability of CdS. © 2004 Elsevier B.V. All rights reserved.

The reduction of CO2 was investigated over zero-valent Fe 0 and Fe0-based composites in an aqueous solution at room temperature. It was found that H2 and a small amount of CH 4 were formed from the CO2-H2O-Fe0 system, while no H2 was formed without CO2. When potassium-promoted Fe0-based composites, Fe0-K-Al and Fe0-Cu-K-Al, were used, the CO2 reduction rates were increased and CH4, C3H8, CH3OH, and C2H5OH were produced together with H2. The fresh and used Fe0 powders after the reaction were analyzed by XPS, XRD, and photoemission yield measurements. The obtained results suggest that in the presence of CO2 as a proton source zero-valent Fe0 is readily oxidized to produce H2 stoichiometrically and that CO 2 is reduced catalytically over the Fe0-based composites with the resulting H2 to produce hydrocarbons and alcohols.
