Effect of functional group on photochemical properties and photosensitization of TiO2 electrode sensitized by porphyrin derivatives
TL;DR: A series of porphyrin derivatives containing carboxylic-, sulfo- and hydro- groups were examined as sensitizers for porous nanocrystalline TiO2 as discussed by the authors.

Preparation and properties of nanostructured TiO2 electrode by a polymer organic-medium screen-printing technique
Tingli Ma,Tetsuya Kida,Morito Akiyama,Kozo Inoue,Shuji Tsunematsu,Ken Yao,Hiroaki Noma,Eiichi Abe +7 more
TL;DR: In this article, an organic medium screenprinting technique was developed for making porous TiO2 electrodes, which were used for dye-sensitized solar cells. But the TiO 2 electrodes have a very porous structure with large cavities.

Photoelectrochemical properties of TiO2 electrodes sensitized by porphyrin derivatives with different numbers of carboxyl groups
Tingli Ma,Kozo Inoue,Ken Yao,Hiroaki Noma,Tsunematsu Shuji,Eiichi Abe,Junhua Yu,Xuesong Wang,Baowen Zhang +8 more
TL;DR: In this article, the photochemical and photoelectrochemical properties of two porphyrin derivatives with different numbers of carboxyl groups were investigated, and it was shown that the variation in the number of functional groups has an influence on the fluorescence spectra of the adsorbed TiO2 electrode.

Effect of Polyelectrolyte Dispersants on the Preparation of Silica‐Coated Zinc Oxide Particles in Aqueous Media
Hongzhi Wang,Hiroyuki Nakamura,Ken Yao,Masato Uehara,Satoshi Nishimura,Hideaki Maeda,Eiichi Abe +6 more
TL;DR: In this article, two kinds of polyelectrolyte dispersants were used to control the surface charge of the ZnO particles in aqueous media, and the results showed that poly(ethylenimine) (PEI) shifted the isoelectric point from pH 9 to pH 10, and poly(ammonium acrylate) (PAA) made the surface charges of ZnOs negative between pH 6 and pH 11.

Spectroscopic and photoelectrochemical study of sensitized layered niobate K4Nb6O17
Ken Yao,Satoshi Nishimura,Yusuke Imai,Hongzhi Wang,Tingli Ma,Eiichi Abe,Hiroshi Tateyama,Akihiko Yamagishi +7 more
TL;DR: In this article, the results are interpreted in terms of the stronger interaction between racemic [Ru(bpy)3]2+ molecules in the interlayer spaces of K4Nb6O17.
