Atmospheric gas as well as UV irradiation is essential for the enhancement, and these enhancement and de-enhancement processes are almost completely reversible. The emission of CdS nanoparticles doped in a PMMA film is also quenched by applying an external electric field, suggesting that the non-radiative decay rate from the emissive exciton state is accelerated by an external electric field.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ OHT・2006 (full paper)　《7》 OTHERS［received 2004/07/02］</FONT> <IMG SRC='/image/misc/huscap.png' HEIGHT=15 VARIGN=bottom></SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Ohara, Y.; Nakabayashi, T.; <B>Iwasaki, K.</B>; <B>Torimoto, T.</B>; <B>Ohtani, B.</B>; Ohta, N.*, Photo-switching behavior of CdS nanoparticles doped in a polymer film, <I>Compt.

Organic compound Ti(OC4H9)4 was used as the titanium, oxygen, and carbon source, while argon served as the carrier gas. The effect of the temperature, substrate, and the flow rate of the carrier gas is investigated. The diameter of the formed carbon-doped TiO2 spheres can be adjusted from 100 nm to several micrometers by varying the flow rate of the carrier gas. The as-prepared TiO2 nanotubes are highly ordered with a diameter of about 100 nm and a wall thickness of around 15 nm. The estimated optical band gap is 2.78 eV for the formed carbon-doped TiO2 microspheres and 2.72 eV for the synthesized carbon-doped TiO2 nanotubes, both of which are much smaller than that of bulk anatase TiO2 (3.20 eV). The photocurrent of the carbon-doped TiO2 spheres is much higher than that of commercial P-25, which is currently considered as one of the best TiO2 photocatalysts, especially under visible light irradiation. The possible mechanism of the formation of TiO2 spheres and nanotubes is also discussed.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ TIC・2007 (full paper)　《260》 VISIBL_E［accepted 2007/07/02］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD>Wu, G.; <B>Nishikawa, T.</B>; <B>Ohtani, B.</B>; <B>Chen, A.</B>*, Synthesis and characterization of carbon doped TiO<SUB>2</SUB> nanostructures with enhanced visible light response, <I>Chem.

Gold modified titania exhibited much higher photocatalytic activity during methanol dehydrogenation under UV irradiation than titania modified with monometallic silver and bimetallic Au-Ag NPs. Bimetallic photocatalysts exhibited either enhanced or reduced visible light activity, depending on properties of noble metal NPs, sequence of their deposition on titania, and properties of host titania. Though numerical simulation (3D-FDTD) showed strong plasmonic field enhancement at the interface between titania and bimetallic core(Au)-shell(Ag) NP, it is thought that co-deposition caused an enhancement of charge carriers recombination (by electron sinking in nearby second metal) inhibiting photoactivity under visible light irradiation. The highest level of photoactivity showed large rutile NPs with successively deposited metals, mainly in the form of individual monometallic NPs, due to size/shape polydispersity of deposited NPs, and thus with ability of light absorption in a broad wavelength range.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ GOSLA・2014 (full paper)　《69》 VISIBL_A［received 2013/07/02］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Kowalska, E.</B>; <B>Janczarek, M.</B>; Rosa, L.; Juodkazis, S.; <B>Ohtani, B.</B>, Mono- and bi-metallic plasmonic photocatalysts for degradation of organic compounds under UV and visible light irradiation, <I>Catal.

DAPs have been synthesized from titanium chloride (TiCl4) through a gas-phase reaction process by rapid heating and quenching. DAPs with well-defined {101} and {001} facets were synthetized and dispersed onto the zeolites. The incorporation of an 8wt% of DAPs into the zeolites has been achieved by means of the freezing-drying technique. Two types of zeolites (ZSM-5 and zeolite Y) with different SiO2/Al2O3 contents have been selected as adsorbents. The photocatalytic properties for the degradation of representative volatile organic compounds (VOC), i.e. acetaldehyde, formaldehyde or trichloroethylene were analyzed under batch and continuous flow reactors. Raw materials and composites were characterized by SEM, N2 adsorption-desorption, UV-vis spectroscopy, XRD, zeta potential and the amount of VOC adsorbed was measured at dynamic conditions. Zeolite/DAP hybrids combine the textural and crystalline properties of zeolite and DAPs phases. The zeolite type (crystal structure, SiO2/Al2O3 ratio and surface net charge) play a relevant role in the dispersion of DAPs. Zeolite/DAP composites show better photocatalytic performance than those prepared with commercial TiO2 due to the presence of {001} facets in the former. The composites prepared with hydrophobic ZSM-5 and DAPs, are the most versatile materials for photooxidation of aldehydes and organochloride compounds, with substantially less formation of non-desirable reaction products respect to those based on benchmark TiO2.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ IJDEC・2017 (full paper)　《38》 ACTIVE［received 2016/07/02］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Jansson, I.</B>; <B>Kobayashi, K.</B>; <B>Hori, H.</B>; Sanchez, B.; <B>Ohtani, B.</B>; Suarez, S.*, Decahedral anatase titania particles immobilized on zeolitic materials for photocatalytic degradation of VOC, <I>Catal.
