A TiO2/graphitic carbon nanocomposites were synthesized by thermal modification in the presence of benzene vapours at different temperature (300-700 °C). The new materials were characterized by a various techniques, such as: X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (UV-vis/DR), surface-enhanced Raman spectroscopy. BET specific surface area was also measured. The photocatalytic activity of obtained nanocomposites was measured by the decomposition of acetic acid and methylene blue under UV-vis irradiation. The results show that photocatalytic activity increasing with increase in carbon concentration and temperature of modification. It can be noted that adsorption degree has a very high impact on methylene blue decomposition. The highest photocatalytic activity was found for the photocatalyst modified at 600 °C contains 1.13 wt% of carbon. It should be noted that, the influence of crystallite size, crystal structure changes and specific surface area for photocatalytic activity are presented.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ AWASS・2018 (Full Paper)　《20》 ACTIVE［received 2017/05/17］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Wanag, A.*; Kusiak-Nejman, E.; Kowalczyk, L.; Kapica-Kozar, J.; <B>Ohtani, B.</B>; Morawski, A.

Herein, we have designed a photocatalyst with a hierarchical structure by photodepositing gold (Au) on the (040) facet of decahedral bismuth vanadate (BiVO4) and then loading zinc rhodium oxide (ZnRh2O4) on the Au surface. Owing to the facet-dependent charge separation property of the decahedral BiVO4, photoexcited electrons in BiVO4 accumulate at the (040) facet and then transfer to Au, which acts as a solid electron mediator, to combine with holes of ZnRh2O4. Utilizing the thus-constructed Z-scheme photocatalyst (ZnRh2O4/Au/BiVO4), the simultaneous liberation of hydrogen (H2) and oxygen (O2) from water at a molar ratio of 2:1 was achieved under irradiation with visible light up to a wavelength of 540 nm, whereas neither H2 nor O2 was produced when Au was deposited randomly on the BiVO4 surface. This study provides insight into the rational design of a solid-state Z-scheme photocatalyst using facet-controlled nanoparticles to enhance photocatalytic activity.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ TAKAS・2019 (Full Paper)　《10》 VISIBL_E［published 2019/05/17］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Takashima, T.*; Moriyama, N.; Fujishiro, Y.; Osaki, J.; <B>Takeuchi, S.</B>; <B>Ohtani, B.</B>; Irie, H., Visible-light-induced water splitting on a hierarchically constructed Z-scheme photocatalyst composed of zinc rhodium oxide and bismuth vanadate, <I>J.

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)　《52》 ETRAPD［accepted 2020/05/17］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Chuaicham, C.; Pawar, R.
