NN 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 NN bond cleavage via 4e−-reduction; only photoisomerization occurs in the absence of TiO2.
