The field of photocatalysis can be traced back more than 80 years to early observations of
the chalking of titania-based paints and to studies of the darkening of metal oxides in contact …

Polymer electrolyte fuel cells (PEFCs) are promising power sources in portable and
transportation applications because of their high energy densities, low operating …

The kinetics of 02reduction accompanying oxidation of organic compounds on
photocatalytic semiconductor particles is analyzed. The rate-controlling processes are …

ABSTRACT A key issue in the photoassisted oxidation of organic materials, eg, oil slicks on
sea water, on semiconducting particles is the charging of the particles by electrons as a …

A non-platinum cathode electrocatalyst must have the stability and catalytic activity for the
oxygen reduction reaction (ORR) in order to be used in polymer electrolyte fuel cells …

Recently, we have prepared transparentnanocrystalline films of a number of those
semiconductorswhich have found wide application in electronic, photoelectronic …

Transient absorption spectroscopy (TAS) has been used to study the interfacial electron-
transfer reaction between photogenerated electrons in nanocrystalline titanium dioxide …

Oxygen reduction on anodically formed TiO2 was studied in both alkaline and acidic water
solutions, using dc voltammetry combined with the rotating disk technique. The possible …

Hypothesis Unlike noble metals, the oxygen reduction reaction (ORR) behavior on Ti is
more complicated due to its spontaneously formed oxide film. This film results in sluggish …

TiO2 powders with various surface hydroxyl densities have been prepared by thermal
treatment (600–1000° C), and their activity for photocatalytic oxygen evolution in aqueous …
