Scanning electron microscope (SEM) observation and analyses of the BET surface area suggested that the powder has a void space between Pt-SrTiO3 (core) and silica (shell). When the surface of the powder was partially modified with a fluoroalkylsilylation agent, thus-obtained material assembled at a gas-water interface and acted as a photocatalyst for overall water splitting to produce hydrogen (H2) and oxygen (O2). Probably due to the suppression of a backward reaction, production of water from H2 and O2, on the platinum, the overall efficiency of this system was higher than that of the conventional suspension system. Moreover, while the Pt-SrTiO3 powders directly covered with fluoroalkylethylsilyl groups showed low photostability, i.e., prolonged irradiation precipitated some of the surface-modified particles in water owing to photocatalytic decomposition of surface fluoroalkylethylsilyl groups, this material could retain its location at the phase boundary.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ STO・2006 (full paper)　《44》 ANISOT_B［published online 2006/06/16］</FONT> <IMG SRC='/image/misc/huscap.png' HEIGHT=15 VARIGN=bottom></SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Ikeda, S.</B>*; Hirao, K.; Ishino, S.; Matsumura, M.; <B>Ohtani, B.</B>, Preparation of platinized strontium titanate covered with hollow silica and its activity for overall water splitting in a novel phase-boundary photocatalytic system, <I>Catal.

The photocatalytic activities were tested for anaerobic methanol dehydrogenation in two reaction systems: (1) under UV/vis polychromatic irradiation with in situ platinum (Pt) deposition, and (2) under UV/vis monochromatic irradiation (action spectra) for ex situ platinum deposition. The properties of bare and modified titania samples were investigated by XRD, DRS, STEM, BET and zeta potential measurements. It was found that platinized rutile was more active than platinized anatase and platinized HomoP25, due to ability of photoabsorption of more photons (narrower band gap). Moreover, in HomoP25 sample, rutile was platinized first, probably due to positively charged surface allowing favorable adsorption of chloroplatinate ions. More than 10 times lower content of Pt (&lt;0.1 wt%) deposited on annealed samples (forming aggregates with an increased interface between titania NPs) than that on HomoP25 (2 wt%) resulted in similar level of photocatalytic activity, suggesting an interparticle electron transfer (IPET) between titania NPs inside one aggregates (one Pt NP was sufficient for one aggregate).'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ KWPTF・2018 (full paper)　《61》 MECHAN［received 2017/06/16］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Wang, K.</B>; <B>Wei, Z.</B>; <B>Ohtani, B.</B>; <B>Kowalska, E.</B>*, Interparticle electron transfer in methanol dehydrogenation on platinum-loaded titania particles prepared from P25, <I>Catal.
