The photoreaction of TiO2 and Au/TiO2 single crystal and ...
TiO 2 and TiO 2-based materials are prototypes for photo-catalytic reactions as they have been shown for many decades to be active for total oxidation of hydrocarbons to clean the environment. In the last decade or so there has been a shift in the objectives for photoreactions mainly towards hydrogen production from renewables. Here we review the fundamentals behind the reactivity of model TiO ...

May 15, 2018· In order to probe into this, hydrogen production rates from ethanol over Au clusters with different sizes deposited on TiO 2 (110) rutile single crystal, were studied by scanning tunneling microscopy (STM) and online mass spectrometry. A non-linear increase of the rate of hydrogen with increasing surface coverage of gold was observed.

Abstract: (Invited) Ethanol Photoreaction over Anatase TiO ...
The reactions of ethanol have been investigated over anatase TiO 2 (101) and rutile TiO 2 (110) single crystals by STM and on-line mass spectrometry to determine the adsorbate species in the dark and post UV illumination, in the presence and absence of O 2 or Au nanoclusters, in order to extract initial reaction parameters under photo-excitation. On anatase (101) TiO 2 single crystal the ...

Abstract - Harvard University
Abstract In this work we present an overview of the photo-reaction of ethanol over the surface of TiO2 (110) single crystal under photo-excitation and compare it to that over Au/TiO 2 nano-particle. Over rutile TiO 2 (110) surface ethanol is present mainly in ethoxide (CH3CH2O(a)) form at 300K as evidenced by the presence of XPS C1s peak at 286.5 eV due to the -CH2-O(a) function; (a) for adsorbed.
