N bond cleavage of azobenzene through
Pt/TiO2 photocatalytic reduction
Abstract
TiO2 photocatalytic 2e−-reduction
of azobenzene to hydrazobenzene is found to occur at λex
> 300 nm while loading of nanometer-sized Pt particles on
TiO2 induces N
N bond cleavage via
4e−-reduction; only photoisomerization occurs in the
absence of TiO2.
