The main photocatalytic products were truns- and cis-5,6dihydroxy-5,6-dihydrothymines (cis- and trans-TG) and N1-formyl-N2-pyruvylurea (FPU). The coformation of the hydroperoxy derivative (6(5)-hydroperoxy-5(6)-hydroxy5,6-dihydrothymine, HTP) and hydrogen peroxide was revealed.  Loading platinum black onto TiO2 enhanced the decomposition of thymine (20% conversion) and the hydroperoxides.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ TTH・1987 (preliminary note)　《5》 OTHERS［received 1987/05/26］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Ohtani, B.</B>; Nagasaki, H.; Nishimoto, S.-i.; Kagiya, T., Photoinduced Oxygenation of Thymine in an Aqueous Suspension of Titanium Dioxide, <I>J.

A part the external surface of silica (SiO2) particles loaded with titanium(IV) oxides was modified with hydrophobic alkyl groups to obtain amphiphilic particles, having both hydrophobic and hydrophilic surfaces on each particle. The amphiphilic particles were spontaneously assembled at interfaces between dual phase mixtures of aqueous solutions and water-immiscible organic compounds. Upon addition to a dual phase mixture of aqueous H2O2 and toluene-containing hydrophobic alcohols, these particles acted as an efficient catalyst for the reaction, to produce corresponding aldehydes and ketones selectively. Notable features of the PBC system are that the oxidation proceeds even without agitation and that only a few percent of titanium species was detected as dissolved species. Productions of aldehydes and ketones were also observed when titanium loaded SiO2 without modification with alkyl groups was employed for the reaction. However, a large amount of titanium loaded on the material was leached during the reaction. These results indicate that surface-covered alkyl groups not only bring about effective contact with hydrophobic alcohols in the organic phase but also give stability against leaching, leading to heterogeneous catalytic functions.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ CHO・2005 (full paper)　《19》 ANISOT_B［received 2004/05/26］</FONT> <IMG SRC='/image/misc/huscap.png' HEIGHT=15 VARIGN=bottom></SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Choi, K.-M.; <B>Ikeda, S.</B>; Ishino, S.; Ikeue, K.; Matsumura, M.; <B>Ohtani, B.</B>*, Oxidation of hydrophobic alcohols using aqueous hydrogen peroxide over amphiphilic silica particles loaded with titanium(IV) oxide as a liquid-liquid phase-boundary catalyst, <I>Appl.

In the present study, a composite of natural sepiolite clay and synthetic graphitic carbon nitride (CN) mixed with dispersed palladium nanoparticles was developed for the efficient photocatalytic degradation of ciprofloxacin (CIP) under visible light irradiation. The sepiolite, CN, and composite materials were characterized by several techniques. The sepiolite/CN composite (SC30%) displayed superior activity than pristine sepiolite and CN, resulted from the generation of new electron trap states in the interfacial contract between sepiolite and CN to suppress the charge recombination of CN. Furthermore, the well-dispersed of 1 wt% Pd-nanoparticles in the SC30% composite collectively enhanced CIP degradation by avoiding the recombination of photogenerated electrons and holes. Additionally, the electron trap states on the surface of all samples were studied using novel reversed double-beam photoacoustic spectroscopy to understand electron transfer in the composites related to the photocatalytic degradation mechanism of CIP. The developed sepiolite/CN/Pd(0) composite can act as a potential catalyst for the degradation of organic pollutants in wastewater under visible light irradiation.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ SEPIO・2020 (Full Paper)　《70》 ETRAPD［published online 2020/05/26］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Chuaicham, C.; Pawar, R.
